ZOOSK, INC.

Overview

We are a leading global
online dating platform with over 26 million members, including approximately 650,000 subscribers, across 80 countries as of December 31, 2013.* We help our members date smarter by leveraging data generated by their actions on our platform.
Our proprietary Behavioral Matchmaking engine continuously learns from the clicks, messaging and other actions of our members in order to deliver connections that are predicted to result in mutual attraction. These connections occur on our unified
global platform, allowing our members to discover and communicate with each other from their mobile phones, tablets or personal computers. We provide our members with highly personalized online dating experiences through easy-to-use features and
adaptive technology. We were the #1 grossing dating app and a top 25 grossing app on the iPhone in the United States as of December 31, 2013. Our solution is offered to our members worldwide through our single brand and is localized in 25
languages.

We launched in 2007 with the belief that online dating would become so common that people would simply think of it as dating.
Traditionally, it was difficult for singles to discover and connect with each other because they were limited by social circles, geography and time. Today, online dating has significantly reduced these limitations and improved the opportunity for
singles to connect. While online dating has increased the number of accessible singles, we believe it has exacerbated the search problem of finding mutual attraction, which can be complex and time-consuming. According to the U.S. Census Bureau,
there were over 100 million unmarried adults in the United States in 2012, and we estimate there to be over one billion unmarried adults worldwide.

Our Behavioral Matchmaking engine is self-learning and dynamically adapts based on member actions on our platform, such as sending a message,
accepting a connection or expressing interest through certain premium features. Our technology processes these actions to present potential connections that are predicted to result in mutual attraction. As we collect more data, our algorithms are
continuously refined to enhance the effectiveness of our solution for all our members.

Our solution is easy to use and fun for our
members. Once a member enters his or her email address and basic information, he or she can discover and connect with other members right away. Our Behavioral Matchmaking engine then starts to capture data, learn preferences and personalize the
experience for that member. We offer our members multiple, distinct discovery tools such as Carousel, Search and SmartPickall powered by our Behavioral Matchmaking engine. These tools and other features, such as Boost and chat, provide our
members multiple ways to interact with each other.

We believe our solution is well suited for mobile devices. Our intuitive mobile
interface and one-touch features allow our members to engage with our platform throughout their day. The availability of our platform across mobile phones, tablets and personal computers enables our members to seamlessly move

*

For a definition of members and subscribers, see Managements Discussion and Analysis of Financial Condition and Results of OperationsKey Metrics.

between devices, increasing the opportunities for member engagement and real-time interactions. During 2013, members using mobile devices had an average of 32% more sessions per day than members
using personal computers. We were the #1 grossing dating app and a top 25 grossing app on the iPhone in the United States as of December 31, 2013 and our Android app has been downloaded over ten million times.

We generate revenues from subscriptions as well as virtual currency. Our member base has experienced rapid growth and we intend to continue to
scale our investments in marketing and focus our efforts on the acquisition of new members and subscribers. Our number of members grew from over 18 million as of December 31, 2012 to over 26 million as of December 31, 2013.
During the same period, our number of subscribers grew from approximately 483,000 to approximately 650,000. Our total revenues grew by 63% from $109.1 million to $178.2 million in 2012 and 2013, respectively. We had net losses of $20.7 million and
$2.6 million in 2012 and 2013, respectively.

Industry Overview

Dating is typically episodic. A person may be single or in a relationship multiple times and for varying periods of time. Traditionally, the
ability for singles to meet was limited by social circles, geography and time. Today, technology, mobile devices and the Internet have significantly reduced these limitations and improved the opportunity for singles to connect. At the same time,
social acceptance of online dating has increased, resulting in more singles embracing online dating as a fun and effective way to meet other singles.

While online dating has increased the number of accessible singles, it has created a search problem that requires users to look through a
large pool of potential candidates in hopes of finding mutual attraction. Some dating websites have tried to solve this search problem through user-generated search constraints to narrow the number of potential matches. Other dating websites have
applied psychology-based methods to attempt to eliminate the need for search altogether by recommending potential matches based on lengthy compatibility-based questionnaires. These websites rely on time-consuming processes and potentially inaccurate
self-assessments, producing static, predefined results. Others attempt to solve the search problem by limiting their members to particular religions, ages, careers, education levels or even food preferences.

Numerous online dating websites and apps have been created, resulting in a highly fragmented marketplace. However, few reach a critical mass
of members. According to IBISWorld, the majority of dating services companies had less than 1% market share of the U.S. dating services market in 2013.

The U.S. online dating market is estimated to be $1.4 billion, according to IBISWorld. The global online dating market is significantly larger
as this estimate does not take into account international markets. Also, we believe the proliferation of mobile devices in both U.S. and international markets will further drive the scale and growth of online dating.

Our Opportunity

We believe that there
is a significant opportunity to help singles date smarter by leveraging behavioral data. Technology platforms such as Amazon, Netflix and Pandora have successfully used data generated by the actions of their customers to enhance their services and
offer recommendations predicted to appeal to each individual customer.

We have applied this behavior-based approach to online dating. By
leveraging behavioral data, we are able to address the complex and time-consuming search problem created by the increased number of accessible singles made possible by online dating. Our data-driven approach provides predictions of mutual attraction
to help members discover and connect with other members.

We provide our members with highly personalized online dating experiences through easy-to-use features and adaptive technology. We believe our
platform provides the following benefits to our members:



Personalized. We create a personalized experience for each and every member. While other online dating websites often bucket their users into predefined, static groups, our Behavioral Matchmaking engine
dynamically processes, learns and adapts to each members unique actions on our platform.



Easy. We make it easy for our members to get started quickly and focus on engaging with other members. After providing an email address and basic information, members can discover and connect with other
members right away.



Mobile. The availability of our platform across mobile phones, tablets and personal computers enables our members to seamlessly move between devices, increasing the opportunities for member engagement and
real-time interactions.



Flexible. Our platform can be used by members throughout their dating lives. We have members who range from 18 to over 90 years old. We seek to form long-term relationships with our members so they return
to our platform each time they are looking for a new dating relationship.



Global. Our global platform serves members across 80 countries in 25 languages and accepts payments in 55 currencies. In 2013, 49% of our total revenues were international, and 62% of our members were
international at the end of the year.



Authentic. We believe that the authenticity and quality of member profiles is important in creating an engaging and meaningful online dating experience for our members. Our member operations team is
dedicated to managing the quality of member profiles by reviewing profile content for compliance with our terms and policies.

Our
Competitive Strengths



Product focus. We aim to provide the most useful and powerful matching technology. Although our matching technology is complex, our interface provides a simple and intuitive way for members to find
potential connections.



Proprietary technology. We typically process and analyze over 45 million member actions per day through our Behavioral Matchmaking engine to dynamically address each members preferences at
scale.



Efficient global platform. We have a single platform that allows our members to access our product through their mobile phones, tablets and personal computers across 80 countries and in 25 languages.



Optimized for mobile. Our product is designed to be easy to use on small screens and enables members to sign up, engage and pay with their mobile devices. During 2013, 41% of our first-time subscriptions
were purchased using mobile devices.



Large member base. Our platform served over 26 million members globally as of December 31, 2013. Our members have a large pool
of singles with whom they can interact and be matched. As

we collect more data from these actions, our algorithms are further refined to enhance the effectiveness of our solution for all our members.



Data-driven business operations. We perform extensive data analysis to make decisions and improve operations across multiple functions of our company, including marketing, product development, member
operations, finance and human resources.

Our Strategy

We intend to continue to strengthen our position as a leading global online dating platform. We have over 26 million members and intend
to grow our member base with the following key strategies:

Mobile leadership. We intend to continue to develop and introduce mobile-optimized features that allow members to quickly view potential connections and express interest through a single touch.



Return-focused advertising. We seek to optimize for total return on advertising spend by frequently analyzing and adjusting this spend to focus on channels and markets that generate a high return.



Brand building. We plan to further increase our brand awareness and build trust with our members through increased public relations, social media and advertising.



Long-term member engagement. We will continue to make it easy for our members to return and receive an optimal experience each time they are looking for a new dating relationship.

Risk Factors

Our business is subject to
numerous risks and uncertainties, including those highlighted in the section entitled Risk Factors immediately following this prospectus summary. These risks include the following:



our limited operating history makes it difficult to evaluate our current business and future prospects;



we have a history of losses, anticipate increasing our operating expenses in the future, and may not achieve or sustain profitability in the future;



if we fail to retain existing members and subscribers or add new members and subscribers, or if our members and subscribers decrease their level of engagement with our platform, our business may be adversely affected;



we spend significant amounts on advertising campaigns to acquire new members and subscribers, which may not be successful or cost-effective;



the market in which we participate is fragmented and highly competitive and if we do not compete effectively, our prospects, operating results and financial condition could be adversely affected;



our number of members is significantly higher than our number of subscribers, and our business will be harmed if we are unable to attract new subscribers;



changes to the standard terms, conditions and policies of third-party platforms that distribute our apps, such as Apple, Facebook and Google, could adversely affect our business;

if use of our platform on mobile devices does not continue to grow or we are unable to continue to successfully deliver and monetize our platform on mobile devices, our business could be harmed;



our quarterly operating results or other operating metrics may fluctuate significantly, which could cause the trading price of our common stock to decline; and



our directors, executive officers and principal stockholders will beneficially own, in the aggregate, approximately % of our shares of outstanding common stock after this offering and, if they
acted together, could have control over the outcome of matters submitted to stockholders for approval or could delay or prevent a change in corporate control.

Corporate Information

We were
incorporated in the State of Delaware in April 2007. Unless expressly indicated or the context indicates otherwise, as used in this prospectus, the terms Zoosk, we, us and our refer to Zoosk, Inc., a
Delaware corporation, and, where appropriate, its subsidiary taken as a whole. Our principal executive offices are located at 989 Market Street, Fifth Floor, San Francisco, California 94103 and our telephone number is (415) 728-9598. Our
website address is www.zoosk.com. Information contained on, or that can be accessed through, our website is not incorporated by reference into this prospectus, and you should not consider information on our website to be part of this prospectus.

Zoosk, the Zoosk logo and other registered or common law trade names, trademarks or service marks of Zoosk appearing in this prospectus
are the property of Zoosk. This prospectus contains additional trade names, trademarks and service marks of other companies that are the property of their respective owners. We do not intend our use or display of other companies trade names,
trademarks or service marks to imply a relationship with, or endorsement or sponsorship of us by, these other companies.

JOBS Act

We are an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012 (JOBS Act). We will
remain an emerging growth company until the earlier of the last day of the fiscal year following the fifth anniversary of the completion of this offering, the last day of the fiscal year in which we have total annual gross revenues of at least $1.0
billion, the date on which we are deemed to be a large accelerated filer (this means that we have been public for at least 12 months, have filed at least one annual report and the market value of our common stock that is held by non-affiliates
exceeds $700 million as of the end of the second quarter of that fiscal year), or the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

In addition, the JOBS Act provides that an emerging growth company can delay adopting new or revised accounting standards until such time as
those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption and, therefore, we will be subject to the same new or revised accounting standards as other public companies that are not emerging
growth companies.

option to purchase additional shares in full, based on an assumed initial public offering price of $ per share, the midpoint of the price range set forth on the cover page of this prospectus, and after
deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us.

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below,
together with all of the other information in this prospectus, including our consolidated financial statements and related notes, before investing in our common stock. The risks and uncertainties described below are not the only ones we face.
Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that affect us. If any of the following risks occur, our business, financial condition, operating results and
prospects could be materially harmed. In that event, the price of our common stock could decline, and you could lose part or all of your investment.

Risks Related to Our Business and Our Industry

Our limited operating history makes it difficult to evaluate our current business and future prospects.

We were founded in 2007 and have a limited history operating our business at its current scale, which makes it difficult to evaluate our
current business and future prospects, including our ability to plan for and model future growth. Although we have experienced significant revenue growth rates in recent periods, you should not rely on our historical growth rates as an indication of
future growth rates. We have encountered and will continue to encounter risks and difficulties as our company and our industry evolve. If we do not address these risks successfully, our business and operating results will be adversely affected, and
our stock price could decline. Further, we operate in a rapidly evolving market. As such, any predictions about our future revenues and expenses may not be as accurate as they would be if we had a longer operating history or operated in a more
predictable market.

We have a history of losses, anticipate increasing our operating expenses in the future, and may not achieve or sustain
profitability in the future.

We have incurred net losses in all fiscal years since our inception, including net losses of $12.2
million, $20.7 million and $2.6 million in 2011, 2012 and 2013, respectively. As of December 31, 2013, we had an accumulated deficit of $95.6 million. We anticipate that our operating expenses will increase substantially in the
foreseeable future as we continue to increase our marketing expenditures to broaden our member and subscriber base and brand awareness, enhance our platform and its features and functionality, expand our operations, hire additional employees and
continue to develop our technology. These efforts may prove more expensive than we currently anticipate, and we may not succeed in increasing our revenues sufficiently, or at all, to offset these higher expenses. Growth of our revenues may slow or
revenues may decline for a number of possible reasons, including slowing demand for our platform, decreasing return on our advertising spend, increasing competition or decreasing growth of our overall market. If we are unable to meet these risks and
challenges as we encounter them, our business may suffer. If we do achieve profitability, we may not be able to sustain or increase such profitability.

If we fail to retain existing members and subscribers or add new members and subscribers, or if our members and subscribers decrease their level of
engagement with our platform, our business may be adversely affected.

The scale and engagement of our member and subscriber base
are critical to our success. Our financial performance has been and will continue to be significantly determined by our success in adding, retaining and engaging members and subscribers. If people do not perceive our platform to be useful, reliable
and trustworthy, we may not be able to attract or retain members or subscribers or maintain or increase the frequency and duration of their engagement. We may experience an erosion of our member and subscriber base or engagement levels. Our member
and subscriber behavior has changed over time and can be difficult to predict, particularly as we introduce new, and modify existing, features and functionality. Any number of factors could negatively affect the size and engagement of our member and
subscriber base, including if:



we are unable to maintain a sufficient member base in certain regions and among certain demographics, making our platform less useful to existing and prospective members in those regions and demographics;

our Behavioral Matchmaking engine does not recommend relevant connections for our members and subscribers or if we are unable to continue to refine or improve our technology to ensure members and subscribers are
presented with potential connections that are relevant to them or there are changes in member and subscriber sentiment about the quality or usefulness of our platform;



technical or other problems prevent us from delivering our platform and its features in a rapid and reliable manner or otherwise negatively affect the member and subscriber experience;



we are unable to continue to develop products for mobile devices that members and subscribers find engaging or that work with a variety of mobile operating systems and networks;



members increasingly engage with our competitors products or services or other products or services;

there are changes in member and subscriber or the general publics concerns related to privacy and sharing, safety, security or other factors;



we fail to provide adequate customer service to members and subscribers;



we or other companies in our industry are the subject of adverse media reports or other negative publicity; or



there are adverse changes in our services that are mandated by legislation, regulatory authorities or litigation.

Any decrease in the size or engagement of our member or subscriber base could render our platform less attractive to current and potential
members and subscribers, which may have a materially adverse impact on our business, financial condition and operating results.

If our current
members disengage with our platform, if current subscribers do not renew their subscriptions, or if our former members and subscribers do not return to our platform, our business will be harmed.

We must continually add new members and subscribers to replace members or non-renewing subscribers and to grow our member and subscriber base.
Subscribers may choose not to renew their subscriptions for many reasons, including changes in a subscribers relationship status, a desire to use a service offered by one of our competitors or dissatisfaction with our platform. Dating is, by
nature, episodic, and our members and subscribers periodically stop engaging with our platform when they enter into a relationship and may reengage or return to our platform after the relationship ends. If the rate at which our members reengage or
our subscribers renew their subscriptions decreases, or if our former members and subscribers do not return to our platform when they are looking for a new dating relationship, our business, financial condition and operating results may be adversely
affected.

If we fail to recommend connections to our members and subscribers that result in mutual attraction, we may fail to retain existing
members and attract new and former members.

We are continually refining our proprietary Behavioral Matchmaking engine to improve
our suggested connections and the usefulness of our platform to our members and subscribers. We may experience difficulty in refining and improving our Behavioral Matchmaking engine, whether due to unforeseen delays or difficulties in the
development process or otherwise.

If our Behavioral Matchmaking engine does not recommend connections for our members and
subscribers that result in mutual attraction or if we are unable to continue to refine or improve our technology, our platform may fail to meet the expectations of our members and subscribers or otherwise be useful to them. Any resulting decrease in
member and subscriber satisfaction could lessen our ability to retain existing members and subscribers and attract new and former members and subscribers, which could have a material adverse effect on our business.

If members profiles are outdated, inaccurate or contain only basic information, our members may not be able to realize the full potential of our
platform, which could adversely affect the growth of our business.

The value of our platform to our members may decrease if a
significant number of our members profiles are outdated, inaccurate or contain only basic information. Outdated or inaccurate profiles or profiles that contain only basic information could diminish the ability of our members to find relevant
potential connections, such as by impairing the ability of our Behavioral Matchmaking engine to suggest relevant connections. If a significant number of our members do not update their information or provide accurate information when they join our
platform, or if a significant number of profiles contain only basic information, other members may become dissatisfied with our platform, our brand may be negatively affected and our member engagement and member and subscriber base could decline.

We spend significant amounts on advertising campaigns to acquire new members and subscribers, which may not be successful or cost-effective.

We acquire many of our members through paid marketing channels. In 2012 and 2013, marketing expenses were $92.7 million and
$128.7 million, respectively, representing 85% and 72% of our total revenues, respectively. We expect to continue to spend significant amounts to acquire additional members and subscribers. In order to maintain our current revenues and grow our
business, we need to continually optimize advertising campaigns aimed at acquiring new members and subscribers. Our success in these efforts depends, in part, upon our continued ability to promote our platform on third-party websites, such as
Facebook and Google, to whom we pay fees to advertise our platform. If one of our advertisers to which we direct considerable online advertising expenditures, such as Facebook or Google, were to increase their fees, change their interface or
experience disruptions in service, we may incur additional advertising expenses to acquire members and subscribers. If our advertising spend increases, the return on our advertising campaigns may be lower than we anticipate regardless of the
revenues generated by new subscriptions, and our growth rate and operating results may be adversely affected.

If any significant
third-party websites or platforms on which we advertise lose their market position or otherwise fall out of favor with consumers or other factors cause their user bases to stop growing or shrink, we may need to identify alternative channels for
advertising and promoting our platform, which would consume substantial resources and may not be effective, or available at all.

While we
seek to structure our advertising campaigns in the manner that we believe is most likely to encourage individuals to join our platform and purchase subscriptions, we may fail to identify advertising opportunities that satisfy our anticipated return
on advertising spend as we scale our investments in marketing, accurately predict member acquisition or fully understand or estimate the conditions and behaviors that drive member behavior. If for any reason any of our advertising campaigns prove
less successful than anticipated in attracting members and subscribers, we may not be able to recover our advertising spend, and our rate of member and subscriber acquisition may fail to meet market expectations, either of which could have an
adverse effect on our business.

In addition to paid advertising channels, we rely on Internet search engines, such as Google, Bing and
Yahoo, to direct traffic to our website, including our mobile website. If search engine companies change their search methodologies or if our competitors search engine optimization efforts are more successful than ours, the growth of our
member and subscriber base could be adversely affected.

The market in which we participate is fragmented and highly competitive. If we do not compete effectively,
our prospects, operating results and financial condition could be adversely affected.

The online dating industry is intensely
competitive and has few barriers to entry. We primarily compete with large online dating websites and apps in the United States and internationally, such as Match.com, eHarmony.com and Meetic.com. We also face competition from numerous smaller
companies in the online dating market, including a large number of free websites and apps. Our competitors may enjoy competitive advantages, such as greater name and brand recognition, longer operating histories, substantially greater market share,
large existing user bases, better competitive positions in certain geographic regions or user demographics, and substantially greater financial, technical and other resources. These factors may allow our competitors to offer products and services
similar to ours at a lower price, develop different products and services to compete with us and respond more quickly and effectively than we do to new or changing opportunities, technologies, market conditions and user preferences. These
competitors may also engage in more extensive research and development efforts, undertake more far-reaching advertising campaigns and adopt more aggressive pricing policies that may allow them to build larger user bases. Our competitors may
develop products or services that are equal or superior to ours or that achieve greater market acceptance than ours. In addition, new and different types of social discovery may also increase in popularity at the expense of online dating. These
activities could attract members and subscribers away from our platform, reduce our market share and have a material adverse effect on our business, operating results and financial condition.

New competitors, business models and products and services are likely to emerge. If we are not able to compete effectively against our current
or future competitors, the size and level of engagement of our member and subscriber base may decrease, which could materially and adversely affect our business, operating results and financial condition.

Our quarterly operating results or other operating metrics may fluctuate significantly, which could cause the trading price of our common stock to
decline.

Our quarterly operating results and other operating metrics have historically fluctuated and may continue to fluctuate
from quarter to quarter. We expect that this trend will continue as a result of a number of factors, many of which are outside of our control and may be difficult to predict, including:



the timing, size and effectiveness of our advertising campaigns to acquire new members and subscribers;



our ability to maintain or increase the size and engagement of our member and subscriber base, including our ability to maintain or increase the rate at which we attract new subscribers, the duration of subscriptions
they purchase and the number and frequency of repeat subscribers;



levels of virtual currency purchases;



increases or decreases in our revenues and expenses caused by fluctuations in foreign currency exchange rates;



increases in and timing of marketing and other operating expenses that we may incur to grow and expand our operations and to remain competitive;



the rate of growth in mobile usage and our ability to monetize through our mobile apps;



the development and introduction of new products and services by us or our competitors;

changes in the legislative or regulatory environment, such as with respect to privacy;



costs related to the acquisition of businesses, talent, technologies or intellectual property, including potentially significant amortization costs and possible write-downs; and



general economic conditions in either domestic or international markets.

Any one of the
factors above or the cumulative effect of some of the factors referred to above may result in significant fluctuations in our operating results. As a result, comparing our quarterly operating results may not be meaningful.

In addition, in future periods, seasonal variations in member and subscriber behavior may cause fluctuations in our financial results. We may
experience seasonal variation in member and subscriber acquisition and engagement during certain vacation and holiday periods. We may also incur higher marketing expenditures during the fourth quarter of each calendar year due to the higher cost of
advertising during the holiday season. While seasonal trends may affect our quarterly operating results, our recent growth may have overshadowed these effects.

The variability and unpredictability of our quarterly operating results or other operating metrics could result in our failure to meet our
expectations or those of any analysts that cover our company or investors with respect to revenues or other operating results for a particular period. If we fail to meet or exceed such expectations for these or any other reasons, the market price of
our common stock could fall substantially, and we could face costly lawsuits, including securities class action suits.

Our number of members is
significantly higher than our number of subscribers. If we are unable to attract new subscribers, if former subscribers do not return to our platform or if existing subscribers do not renew their subscriptions, our business may be adversely
affected.

Our business model depends in part on attracting and maintaining a large member and subscriber base. It also depends on
former subscribers returning to our platform when they are looking for a new dating relationship and existing subscribers renewing their subscriptions. We generate revenues primarily through subscription sales to our subscribers, who constitute a
relatively small portion of our overall member base, as well as through sales of virtual currency to our members and subscribers. Subscription fees accounted for 95% and 86% of our total revenues in 2012 and 2013, respectively. If we are unable
to attract new subscribers, if former subscribers do not return to our platform when they are looking for a new dating relationship or if existing subscribers do not renew their subscriptions, our business may be adversely affected.

Changes to the standard terms, conditions and policies of third-party platform providers that distribute our apps, such as Apple, Facebook and Google,
could adversely affect our business.

We depend on third-party platform providers to allow members to locate and download our apps
that enable access to our platform, facilitate payments through our mobile apps and streamline member registration. A substantial number of our members and subscribers choose to engage with our platform through mobile apps downloaded from
third-party app stores, such as the Apple App Store and Google Play. Apple also provides

payment processor services for members who purchase subscriptions or virtual currency through our iOS mobile apps. We are subject to the standard terms, conditions and practices of these platform
providers for app developers, which govern the promotion, distribution, operation and use of our apps downloaded from their respective platforms. Platform providers have broad discretion to change their standard terms and conditions and have
the right to prohibit a developer from distributing apps on their platform if the developer violates the standard terms and conditions. In addition, platform providers can change their policies or interpretations of their standard terms and
conditions. Our business could suffer materially if platform providers change their standard terms and conditions, interpretations or other policies and practices in a way that is detrimental to us or if platform providers determine that we are in
violation of their standard terms and conditions and prohibit us from distributing our apps on their platforms. For instance, currently Apple charges a commission on purchases and subscriptions made through its App Store. If other third-party
platform providers begin imposing a fee for sales through their platform, our marketing costs could increase, which could have an adverse impact on our operating results. Moreover, if we are unable to maintain a good relationship with these platform
providers, our business and operating results could be adversely affected. For example, our business would be harmed if these platform providers:



discontinue, limit or restrict access to their platforms by us or our apps;



modify their terms of service or other policies, including restrictions on app developers;



increase or impose commissions on subscription or virtual currency sales through their platforms;



establish more favorable relationships with one or more of our competitors;



develop their own competitive offerings; or



impose fees associated with access to and use of their platforms.

When a new member registers
for our platform using a third-party social network, such as Facebook, our platform may collect information from the social network to enable the member to quickly and easily create a profile. We also use notification systems provided by or through
third-party platforms and social networks to provide certain communications to our members, such as mobile app notifications. Our business could be harmed if these social networks or platforms change their terms and conditions relating to how
information of their users may be shared with us on or through their platforms, change their notification features or capabilities, or restrict how their users can share information with friends on these platforms or across other platforms, which
could impact member acquisition, the quality of member profiles and member engagement.

Our email and text message campaigns are an important means
to drive member and subscriber engagement. Disruptions in, restrictions on or any increase in the costs associated with the sending or receipt of emails or text messages or a decrease in member and subscriber willingness to receive emails and text
messages could adversely affect our revenues and business.

Our email and text message campaigns are an important means to drive
member and subscriber engagement. We send a large volume of emails and text messages to members and subscribers notifying them of a variety of activities on our platform, such as new connections. We also rely on the use of email and text messages as
a part of our registration and validation processes. Because of the importance of email and text messages to our business, if we are unable to successfully deliver emails or text messages to our members and subscribers or if members and subscribers
consistently decline to open our emails or text messages, our business could be adversely affected.

We also face a risk that service
providers or email applications may block bulk message transmissions or otherwise experience technical difficulties that result in our inability to successfully deliver emails or text

messages to our members and subscribers. Third parties may also block our emails as spam, impose restrictions on our emails or text messages, or start to charge for the delivery of emails through
their email systems. In addition, changes in how webmail applications organize and prioritize email may reduce the number of members and subscribers opening our emails. For example, Googles Gmail service recently introduced a new feature that
organizes incoming emails into categories (for example, primary, social and promotions). Such categorization or similar inbox organizational features may result in our emails being delivered in a less prominent location in a members or
subscribers inbox or viewed as spam by our members and subscribers and may reduce the likelihood of that member or subscriber opening our emails.

Email communications and advertising may subject us to potential risks, such as liabilities or claims resulting from unsolicited email or
spamming, lost or misdirected messages, security breaches, illegal or fraudulent use of email or personal information or interruptions or delays in email service. For example, in the United States, the Controlling the Assault of Non-Solicited
Pornography and Marketing Act of 2003 (the CAN-SPAM Act) establishes certain requirements for the distribution of commercial email messages and provides for penalties for transmission of commercial email messages that are
intended to deceive the recipient as to source or content. In addition, some states have passed laws regulating commercial email practices that are, in some cases, significantly more punitive and difficult to comply with than the CAN-SPAM Act. For
instance, we are currently involved in a class action lawsuit asserting claims under Californias anti-spam statute relating to an email advertising campaign that was carried out by a third-party. Such legal claims, if successful, might result
in substantial costs and the diversion of resources or limit or prohibit our ability to send emails.

Text messages may subject us to
potential risks, including liabilities or claims relating to consumer protection laws. For example, the Telephone Consumer Protection Act of 1991 (the TCPA) restricts telemarketing and the use of automatic SMS text messages without
proper consent. The Federal Trade Commission (FTC) has guidelines that impose responsibilities on companies with respect to communications with consumers, such as text messages, and impose fines and liability for failure to comply with
rules with respect to advertising or marketing practices it may deem misleading or deceptive. Furthermore, a number of states and countries have enacted statutes that address telemarketing through SMS text messages. Restrictions on marketing through
text messages are enforced in the United States by the FTC, the Federal Communications Commission (FCC), state agencies and through the availability of statutory damages and class action lawsuits for violations of the TCPA or similar
laws. The scope and interpretation of the laws that are or may be applicable to our use of text messages are continuously evolving and developing. If we do not comply with these laws or regulations or if we become liable under these laws or
regulations, we could be harmed, and we may be forced to implement new marketing methods, which may be costly or ineffective.

Without the
ability to deliver emails and text messages to members and subscribers, we may have limited means of maintaining contact with our members and subscribers and inducing them to use our platform. Due to the importance of email and text messages to our
business, any disruptions or restrictions on the distribution or receipt of emails or text messages or increase in the associated costs could have a material adverse effect on our business and operating results.

If use of our platform on mobile devices does not continue to grow or we are unable to continue to successfully deliver and monetize our platform on
mobile devices, our business could be harmed.

Our future success depends in part on the continued growth in the use of our
platform on mobile devices by our members and subscribers and our continued ability to deliver and monetize our platform on mobile devices. The use of mobile technology may not continue to grow at historical rates, and singles may not continue to
use mobile technology for online dating. Further, mobile technology may not be accepted as a viable long-term platform for a number of reasons, including actual or perceived lack of security of information and possible disruptions of service or
connectivity. In addition, traffic on our mobile apps may not continue to grow if we do not continue to innovate and introduce enhanced products on mobile platforms or if members believe that our competitors offer superior mobile products. If use of
our platform on mobile devices does not continue to grow, or declines, our business and operating results could be harmed.

If we are unable to expand our apps to new devices and third-party platforms, our business could be
adversely affected.

The number of people who access online services through mobile phones and tablets offered by various third
parties has increased dramatically in the past few years. As new devices and new third-party platforms are continually being released, it is difficult to predict the challenges we may encounter in developing new versions of our apps for use on these
alternative devices and third-party platforms, and we may need to devote significant resources to the creation, support and maintenance of our apps on such devices and third-party platforms. If we are unable to successfully expand the devices and
third-party platforms on which our services are available or if the apps that we create for alternative devices and third-party platforms are not compelling to our members or subscribers, our business will suffer.

Our future performance depends in part on the continued functionality and support of third-party operating systems, platforms and browsers, which affect
how members interact with our platform.

We are dependent on the interoperability of our platform with popular mobile operating
systems that we do not control, such as Googles Android and Apples iOS. Any changes in such systems that degrade the functionality of our platform or give preferential treatment to competitive products and services could adversely affect
our business. We also rely on the continued functioning of the app stores of these platform providers because a portion of our revenues is derived from subscription and virtual currency sales through these platforms. Members who purchase
subscriptions or virtual currency from some of these platforms are required to use these platforms to enable or disable automatic renewals of their subscriptions, change the payment method they use for their purchases, cancel their subscriptions and
set certain other preferences. In the event that these platforms are unavailable or if in-app purchasing or preference setting functionality from these platforms is non-operational for a prolonged period of time, our members and subscribers could
become dissatisfied with our platform, which could negatively affect our brand and have a material adverse effect on our revenues and operating results.

We also depend on various Internet web browsers, such as Internet Explorer, Chrome, Firefox and Safari, to allow our members to access our
platform. If Internet web browsers features or specifications are modified in such a way that make them incompatible with our platform or harder for our members and subscribers to use our platform, overall growth in our member and subscriber
base could slow, member and subscriber engagement could decrease, and we could lose existing members and subscribers, which would negatively impact our business.

Our business depends on a strong brand. If events occur that damage our reputation and brand, we may be unable to maintain and grow the size and
engagement of our member and subscriber base, and our business and financial results may be harmed.

We believe that maintaining,
protecting and enhancing our reputation and brand is critical to expanding our member and subscriber base and engagement with our platform. Maintaining, protecting and enhancing our brand will depend largely on our ability to continue to provide
high-quality, useful and innovative services, features and functionality. If members do not perceive our platform to be of high quality, the value of our brand could diminish, thereby decreasing the attractiveness of our platform to members and
prospective members. We also believe that our reputation and brand may be harmed if we fail to maintain a consistently high level of customer service.

Our reputation and brand could also be negatively affected by the actions of members that are hostile, inappropriate or illegal, whether on or
off our platform, or by members with inaccurate profile information. In addition, members and subscribers may become dissatisfied with our billing policies, our handling of personal data or other aspects of our platform. If we fail to adequately
address these or other member complaints, negative publicity about us or our platform could diminish confidence in and the use of our platform. Maintaining, protecting and enhancing our reputation and brand may require us to make substantial
investments, and these

investments may not be successful. Our reputation and brand are also important to attracting and maintaining high-performing employees. If we fail to successfully promote and maintain our
reputation and brand or if we incur significant expenses in this effort, our business and financial results may be adversely affected.

Misuse of
our platform or actions off our platform could damage our reputation and our brand, which in turn could adversely affect our business or financial condition.

Our platform could be used to facilitate illegal or dishonest activities and behavior. Illegal or dishonest activities and behavior by our
members could injure our other members and may jeopardize our reputation and the integrity of our brand. Members could also post fraudulent profiles or create false or unauthorized profiles on behalf of other, non-consenting parties. This behavior
could subject us to liability or lead to negative publicity that could damage our reputation and the reputation of the online dating industry.

The nature of online dating is such that we cannot control the actions of our members in their communications or physical actions. It is
possible that one or more of our members could be physically, financially, emotionally or otherwise harmed following interaction with other members. If one or more of our members suffers or alleges to have suffered physical, financial, emotional or
other harm following contact initiated on our platform or an online dating website of one of our competitors, any resulting negative publicity or legal action could harm our reputation and business and may have an adverse effect on us and the
reputation of the online dating industry in general, potentially leading to, among other things, increased government scrutiny and regulation and an adverse effect on our business, financial condition and operating results.

We are subject to a number of risks related to payment methods, primarily related to accepting credit card and debit card payments.

We accept payments from our members primarily through credit and debit card transactions and certain online payment service providers. If we
are unable to maintain our chargeback or refund rates at levels that credit card and debit card issuers and payment processors deem acceptable, these entities may increase fees for chargeback transactions or for many or all categories of
transactions, or they may terminate their relationship with us. Any increases in fees could adversely affect our operating results, particularly if we elect not to raise the prices for our platform to offset the increase. The termination of our
ability to process payments on any major credit or debit card or through certain online payment service providers or payment processors could significantly impair our ability to operate our business.

We may also incur losses from erroneous transactions on our platform, from members who claim they did not authorize transactions on our
platform. In addition to the direct costs of such losses, if they are related to credit card transactions and become excessive, they could potentially result in the loss of our right to accept credit cards for payment. If we fail to adequately
prevent fraudulent credit card transactions, we may face civil liability, diminished public perception of our security measures and significantly higher credit card-related costs, each of which could adversely affect our business, financial
condition and operating results.

We pay interchange and other fees for credit card, debit card and certain online payment transactions,
and these fees may increase over time. We may not be able to offset any such increases to our operating expenses by increasing the prices we charge for usage of our platform without causing us to lose subscribers and revenues, which would adversely
affect our operating results. As we offer new payment options to our members, we may be subject to additional regulations, compliance requirements and fraud.

We are subject to rules and regulations of payment card associations. Our failure to adhere to such rules and regulations could subject us to damages
and liability and could eventually prevent us from processing or accepting credit card payments.

DSS), a security standard with which companies that collect, store or transmit certain data regarding credit and debit cards, credit and debit card holders and credit and debit card
transactions are required to comply. Our failure to comply fully with the PCI DSS may violate payment card association operating rules, U.S. federal and state laws and regulations and the terms of our contracts with payment processors and merchant
banks. Such failure to comply fully also may subject us to fines, penalties, damages and civil liability and may result in the loss of our ability to accept credit and debit card payments. In addition, there is no guarantee that PCI DSS compliance
will prevent illegal or improper use of our payment systems or the theft, loss or misuse of data pertaining to credit and debit cards, credit and debit card holders and credit and debit card transactions.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our financial condition and operating results.

Revenues from members and subscribers outside the United States accounted for 51% and 49% of our total revenues in 2012 and 2013,
respectively, while only a relatively small portion of our costs were incurred in foreign currencies. Our international revenues are denominated in foreign currencies, and therefore, our revenues are subject to foreign currency risk. We have not
engaged in currency hedging activities to limit the risk of exchange fluctuations and, as a result, our financial condition and operating results could be adversely affected by such fluctuations. Even if we were to implement hedging strategies to
mitigate foreign currency risk, these strategies might not eliminate our exposure to foreign exchange rate fluctuations and would involve costs and risks of their own, such as ongoing management time and expertise, external costs to implement the
strategies and potential accounting implications.

Our future growth plan depends in part on continuing to deepen our market penetration outside of
the United States, and we are therefore subject to a number of risks associated with international operations.

We intend to
continue to offer our platform globally and to use third-party service providers located outside of the United States. International operations are subject to a number of risks, including the following:



fluctuations in exchange rates between the U.S. dollar and foreign currencies in markets where we do business;



difficulties in attracting and retaining personnel located in the United States with experience in the international markets we target;



difficulties in tailoring our platform and its features and advertising campaigns to local custom;

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel. In particular, we are highly
dependent on the contributions of our co-founders, Shayan Zadeh and Alex Mehr, as well as other members of our management team. The loss of any key personnel could make it more difficult to manage our operations and research and development
activities, reduce our employee retention and revenues and impair our ability to compete. Although we have entered into employment offer letters with our key personnel, these agreements have no specific duration and provide for at-will employment,
which means they may terminate their employment relationship with us at any time.

Competition for highly skilled personnel is often
intense, especially in the San Francisco Bay Area where we are located, and we may incur significant costs to attract them. We may not be successful in attracting, integrating or retaining qualified personnel to fulfill our current or future needs.
We have, from time to time, experienced, and we expect to continue to experience, difficulty in hiring and retaining highly skilled employees with appropriate qualifications. In addition, job candidates and existing employees often consider the
value of the equity awards they receive in connection with their employment. If the perceived value of our equity or equity awards declines, it may adversely affect our ability to retain highly skilled employees. We expense all stock-based
compensation, and we may periodically change our stock compensation practices, which may include reducing the number of employees eligible for stock-based awards or reducing the size of equity awards granted per employee. If we fail to attract new
personnel or fail to retain and motivate our current personnel, our business and future growth prospects could be severely harmed.

We collect,
process, share, retain and use personal information and other data, which subjects us to governmental regulations and other legal obligations related to privacy, and our actual or perceived failure to comply with such obligations could harm our
business.

A variety of federal, state and foreign laws and regulations govern privacy and the collection, use, retention, sharing
and security of personal information. We collect, process, use, share and retain personal information and other member data, including information about our members as they interact with our platform, and we have a privacy policy concerning our use
of member data on our platform. Any failure or perceived failure by us to comply with applicable privacy laws and regulations or with our privacy policy or any compromise of security that results in the unauthorized release or transfer of sensitive
information, which may include personally identifiable information or other member data, may result in governmental enforcement actions or litigation, which could be costly to defend and may require us to pay significant fines or damages. Such
failures or perceived failures could also result in public statements against us by consumer advocacy groups, our members or others, which could harm our brand and could cause our members to lose trust in us, which in turn could have an adverse
effect on our business. Additionally, if third parties we work with, such as advertisers, vendors or platform providers, violate applicable laws or our policies, such violations may also put the information of our members at risk and could in turn
have an adverse effect on our business.

We also are or may become required to comply with varying and complex privacy laws and
regulations in multiple jurisdictions, and laws and regulations in foreign jurisdictions are sometimes more restrictive than those in the United States. For example, the European Union and its member states traditionally have taken

broader views as to types of data that are subject to privacy and data protection and have imposed greater legal obligations on companies in this regard. Proposed legislation and regulations
concerning data protection are currently pending at the U.S. federal and state level as well as in certain foreign jurisdictions, and this legislation may impose more stringent operational requirements on us and include significant penalties for
non-compliance. In addition, the interpretation and application of privacy and data protection laws in Europe, the United States and elsewhere are still uncertain and in flux. It is possible that these laws may be interpreted and applied in a
manner that is inconsistent with our practices. If so, in addition to the possibility of fines, this could result in an order requiring that we change our practices, which could have an adverse effect on our business. Complying with these laws as
they evolve could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business.

As a result of our collection, retention and use of personal data, we are or may become subject to diverse laws and regulations in the United
States and foreign jurisdictions mandating notification to affected individuals in the event that personal data (as defined in the various governing laws) is accessed or acquired by unauthorized persons. Complying with such numerous and complex
regulations in the event of unauthorized access would be expensive and difficult, and failure to comply with these regulations could subject us to regulatory scrutiny and additional liability.

Member trust regarding privacy and data security is very important to the growth of our business, and privacy or data security concerns
relating to our platform could damage our reputation and deter current and potential members from using our platform, even if we are in compliance with applicable privacy and data security laws and regulations.

Our business is subject to a variety of U.S. and foreign laws and regulations, many of which are unsettled and still developing and which could subject
us to claims or otherwise harm our business.

We are or may become subject to a variety of laws and regulations in the United
States and abroad that involve matters central to our business, including laws and regulations regarding privacy, data protection, data security, data retention, consumer protection, electronic commerce, intellectual property, online dating and the
provision of online payment services. These laws and regulations are continuously evolving and developing. The scope and interpretation of the laws that are or may be applicable to us are often uncertain and may be conflicting, particularly laws
outside the United States. It is likely that as our business grows and evolves and our platform is used in a greater number of countries, we will become subject to laws and regulations in additional jurisdictions. Our members could also abuse or
misuse our services in ways that violate laws. It is difficult to predict how existing laws will be applied to our business and the new laws to which we may become subject. Furthermore, the growth and development of electronic commerce, online
dating and virtual currency may prompt calls for more stringent consumer protection laws, such as requirements for criminal background checks for users of online dating services, that may impose additional burdens on online dating companies such as
ours conducting business through the Internet and mobile devices. We anticipate that scrutiny and regulation of our industry will increase and that we will be required to devote additional legal and other resources to addressing such regulation. If
that were to occur, we may be required to seek licenses, authorizations or approvals from relevant regulators, the granting of which may depend on us meeting certain capital and other requirements, and we may be subject to additional regulation and
oversight, any of which could significantly increase our operating costs. Changes in current laws or regulations or the imposition of new laws and regulations in the United States or elsewhere regarding these activities may impair our business.

If we are not able to comply with these laws or regulations or if we become liable under these laws or regulations, we could be directly
harmed, and we may be forced to implement new measures to reduce our exposure to this liability. This may require us to expend substantial resources or to discontinue certain products or services, which would negatively affect our business,
financial condition and operating results. In addition, the increased attention focused upon liability issues as a result of lawsuits and legislative proposals could harm our reputation or otherwise impact the growth of our business. Any costs
incurred as a result of this potential liability could harm our business and operating results.

Members may curtail or stop their use of our platform if our security measures are compromised, if our
platform is subject to attacks that degrade or deny the ability of members to access our platform or if our member data is compromised.

Our platform collects, processes, stores, shares, discloses and uses the information of our members and their communications. We are
vulnerable to computer viruses, break-ins, phishing attacks, attempts to overload our servers with denial-of-service and other cyberattacks and similar disruptions from unauthorized use of our computer systems. Our security measures may also be
breached due to employee error, malfeasance or otherwise. Several recent, highly publicized data security breaches and denial of service attacks at other companies have heightened public awareness of this issue and may embolden individuals or groups
to target our systems. Any of the foregoing could lead to interruptions, delays or platform shutdowns, causing loss of critical data or the unauthorized disclosure or use of personally identifiable or other confidential or sensitive information,
such as credit card information or information about our members. If our security is compromised, we could experience platform performance or availability problems, the complete shutdown of our platform or the loss or unauthorized disclosure of
confidential or sensitive information. We could be subject to liability and litigation and reputational harm, and our members may be harmed, lose confidence in us and decrease or terminate the use of our platform.

We also rely on certain third parties to provide critical services and to store sensitive customer information. For example, our platform is
hosted using data centers operated by third parties. However, we have little or no control over the security measures implemented by these parties, and if these measures are compromised, we could be exposed to similar risks and liabilities to those
described above.

Unauthorized parties may also fraudulently induce employees or members to disclose sensitive information in order to
gain access to our information or the information of our members or access this information through other means. They might also abuse our systems in other ways, such as by sending spam, which could diminish or otherwise degrade the experience of
our members or by compromising or gaining unauthorized access to member accounts. Because the techniques used to obtain unauthorized access, disable or degrade service or sabotage systems change frequently and are becoming increasingly
sophisticated, they often are not recognized until launched against a target. Furthermore, such attacks may originate from less regulated and remote areas around the world, and we may be unable to proactively address these techniques or to implement
adequate preventative measures. Any or all of these issues could negatively impact our ability to attract new members and increase engagement by existing members, cause existing members to stop using our platform or subject us to lawsuits,
regulatory fines or other action or liability, thereby harming our business and operating results.

We may be liable as a result of information on
or transmitted through our platform.

We may be sued for defamation, civil rights infringement, negligence, copyright or trademark
infringement, invasion of privacy, personal injury or under other legal theories relating to information that is transmitted, published or made available through our platform by our members or otherwise. These types of claims have been brought,
sometimes successfully, against online services in the past. We could incur significant costs in investigating and defending such claims arising from information on or transmitted through our platform, even if we ultimately are not held
liable. If any of these events occurs, our revenues could be adversely affected or we could incur significant additional expense.

Certain of
our key metrics are subject to challenges in measurement, and real or perceived inaccuracies in such metrics may harm our reputation and negatively affect our business.

We rely on internal data, assumptions and estimates to calculate certain of our operating metrics. We regularly review and adjust our processes
for calculating our operating metrics. For example, historically, we did not record our number of members at each balance sheet date. Accordingly, we calculated our number of

members in this prospectus as of December 31, 2010, 2011, 2012 and 2013 using reports that were generated from our system in January 2014. Due to historical system limitations, however,
these reports exclude from our number of members those members whose profiles were deactivated between the balance sheet date and January 2014. Accordingly, the number of members reported for past dates may be understated as compared to the number
that would have resulted if we had run the report as of the balance sheet date due to subsequent deactivations, which may imply higher growth rates than what actually occurred. See Industry Data and Company Metrics.

Changes to our methodologies may cause our operating metrics to fluctuate and result in future operating metrics that are not as comparable
with operating metrics in prior periods. If investors or analysts who cover our common stock do not perceive our operating metrics to be accurate, or if changes to our methodologies result in different reported results of operating metrics than they
expect, the price of our common stock could be adversely affected.

We have experienced rapid growth in recent periods, and if we fail to manage our
growth effectively, our business and operating results could be harmed.

We have experienced rapid growth over the last few years.
Our employee headcount has increased significantly, and we expect to continue to grow our headcount significantly over the next 12 months. For example, as of December 31, 2013, we had 168 employees, as compared to 105 employees as of
December 31, 2011. This growth has placed substantial demands on our management, operational infrastructure and financial resources.

Our future success will depend, in part, upon our ability to manage growth effectively. Among other things, this may require us to:



hire and manage additional personnel;



effectively integrate, develop and motivate a large number of new employees, while maintaining the beneficial aspects of our company culture;

Our failure to improve our systems and processes, or the
failure of such systems and processes to operate in an intended manner, may result in our inability to manage the growth of our business and to accurately forecast our revenues and expenses or to prevent losses. Our productivity and the quality of
our solution may also be adversely affected if we do not integrate and train our new employees quickly and effectively. If we fail to manage the growth of our business and operations effectively, the quality of our platform and the efficiency of our
operations could suffer, which could harm our brand, business and operating results.

Our platform may contain undetected software errors, which
could harm our business and operating results.

Our platform, including our Behavioral Matchmaking engine and our mobile apps,
incorporates complex software. We encourage employees to quickly develop and help us launch new and innovative features, and some errors in our software code may only be discovered after the software has been incorporated into our

platform and released to our members. Any errors, bugs or vulnerabilities discovered in our code after release could result in disruption to our platform, damage to our reputation, loss of
members or liability for damages, any of which could adversely affect or business and operating results.

We depend on third-party data center
service providers. Any disruption in the operation of the data center facilities or failure to renew the services could adversely affect our business.

Our platform is hosted using data centers operated by third parties. We control neither the operation of the data centers nor our third-party
data center service providers. We have entered into agreements for the lease of our data centers and with third-party data center service providers. Our data center leases and agreements with the data center service providers expire at various
times. The third-party data center service providers may have no obligation to renew their agreements with us on commercially reasonable terms, or at all. If we are unable to renew these agreements on commercially reasonable terms, we may be
required to transfer our servers or data to new data center facilities or engage new service providers, and we may incur significant costs and a possible interruption in our platform in connection with doing so.

Problems with our third-party data center service providers, the telecommunications network providers with whom they contract or with the
systems by which telecommunications providers allocate capacity among their customers could adversely affect the experience of our members. Our third-party data center service providers could decide to close their facilities or cease providing us
services without adequate notice. In addition, any financial difficulties, such as bankruptcy, faced by our third-party data center service providers or parties they contract with may have negative effects on our business, the nature and extent of
which are difficult to predict. Additionally, any failure of our data centers to keep up with our growing needs for capacity could have an adverse effect on our business. Any changes in third-party service levels at our data centers or any errors,
defects, disruptions or other performance problems with our platform could harm our reputation and may damage the data of our members. We have in the past had outages at our data centers, and future interruptions to our platform might reduce our
revenues, cause us to issue refunds to members and subscribers, subject us to potential liability or harm our renewal rates and our ability to attract new subscribers.

Our operating results may be negatively affected if we are required to pay sales tax or other transaction taxes on all or a portion of sales in
jurisdictions where we are currently not collecting and reporting tax.

We currently do not pay sales or other transaction taxes
in every jurisdiction in which we do business. A successful assertion by any jurisdiction that we are required to pay taxes in connection with sales on our platform, or the imposition of new laws requiring the payment of taxes, could create
increased administrative burdens or costs, discourage members from using our platform, decrease our ability to compete, result in substantial tax liabilities related to past sales or otherwise harm our business and operating results.

Our platform contains open source software, which subjects us to various risks.

Our platform incorporates software licensed under open source licenses. The use of open source software may entail greater risks
than the use of third-party commercial software because open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. Certain open source licenses also require
that source code subject to the license be made available to the public and that any modifications or derivative works to open source software continue to be licensed under open source licenses. From time to time, we may face claims from third
parties claiming ownership of, or demanding release of, the open source software or derivative works that we developed using such software, which could include our proprietary source code, or otherwise seeking to enforce the terms of the applicable
open source license. These claims could result in litigation and could require us to pay damages, purchase a costly license or devote additional research and development resources to change our platform, any of which could have a negative effect on
our business and operating results.

In addition, we have chosen to make certain of our technology available under open source
licenses that allow others to use the technology without payment to us. While we hope to benefit from these activities by receiving useful open source technology in return under open source licenses, there is no assurance that we will receive the
business benefits we expect, and it is possible that our competitors will use the technology we make available to compete with us.

Our proprietary
rights may be difficult to enforce or protect, which could enable others to copy or use aspects of our platform without compensating us.

To protect our proprietary rights, we rely, and expect to continue to rely, on a combination of confidentiality agreements with our employees,
consultants and third parties with whom we have relationships, as well as trademark, copyright, patent, trade secret and domain name protection laws. We have filed various applications for certain aspects of our intellectual property in the United
States and internationally. Despite our efforts to protect our proprietary rights, there can be no assurance that these rights will be sufficient to prevent others from offering products or services that are substantially similar to ours and compete
with our business. For example, unauthorized parties may attempt to copy aspects of our platform or obtain and use information that we regard as proprietary, third parties may challenge proprietary rights held by us which could result in such rights
being invalidated or narrowed in scope, pending and future trademark and patent applications may not be approved, the claims eventually allowed on any patents may not be sufficiently broad to protect our technology or products and our trademarks may
not adequately protect our brand. Additionally, the process of obtaining patent or trademark protection is expensive and time-consuming, and we may not be able to prosecute all necessary or desirable patent applications or apply for all necessary or
desirable trademark applications at a reasonable cost or in a timely manner. We may similarly not be able to, or elect not to, apply for or prosecute patents or trademarks in all of the jurisdictions in which we operate or in which our services are
available. We also rely on trade secrets and confidentiality agreements to protect certain of our software source code and to protect our technology in cases when we believe patent protection is not appropriate or obtainable. However, we may not in
all cases have entered into the agreements necessary to protect this information, and even when we have entered into such agreements, they may be breached. Our trade secrets and other confidential information may also be disclosed through other
means, for example as a result of physical or electronic security breaches.

In addition, the laws of some foreign countries do not
protect our proprietary rights to as great an extent as the laws of the United States, and many foreign countries do not enforce these laws as diligently as government agencies and private parties in the United States.

From time to time, we may need to take legal action to enforce our trademarks, patents and other intellectual property rights, to protect our
trade secrets, to determine the validity and scope of the proprietary rights of others or to defend against claims of infringement or invalidity. Such litigation could result in substantial costs and diversion of resources and could negatively
affect our business, operating results, and financial condition. Attempts to enforce our rights against third parties could also provoke these third parties to assert their own intellectual property or other rights against us or result in a holding
that invalidates or narrows the scope of our rights, in whole or in part. Even if we prevail in any enforcement efforts, the remedy we obtain may not be commercially meaningful or adequately compensate us for the damages we have suffered. Any of
these events could have a material adverse effect on our business, financial condition and operating results.

Claims by others that we infringe
their proprietary technology or other rights could harm our business.

Companies in the online dating, social media, software,
Internet and e-commerce industries own large numbers of patents, copyrights, trademarks, domain names and trade secrets, and frequently enter into litigation based on allegations of infringement, misappropriation or other violations of intellectual
property or other rights. For example, we are currently a party to certain lawsuits by non-practicing entities alleging, among other things, patent infringement, including litigation brought by GeoTag Inc., which has brought similar claims against
numerous companies in the United States for alleged infringement of its patent relating to geographic locator

information determined through the Internet. In addition, we may be subject to claims of infringement of intellectual property rights against us in the future. As the number of competitors in our
market increases and overlaps occur, and as our profile within this market grows, the number of patent and other intellectual property claims against us may increase. While we intend to increase the size of our patent portfolio, our competitors and
others may now and in the future have significantly larger and more mature patent portfolios than we have. In addition, future litigation may involve patent holding companies or other adverse patent owners who have no relevant product revenues and
against whom our own patents may therefore provide little or no deterrence or protection. Any claim of infringement by a third party, including patent infringement claims such as those made by GeoTag where we currently believe the likelihood of a
material loss is remote, or that we currently believe are without merit, could cause us to incur substantial costs defending against the claim and could distract our management from our business. Furthermore, a successful claimant could secure a
judgment or we may agree to a settlement that requires us to pay substantial damages, royalties or other fees. Any of these events could seriously harm our business, financial condition and operating results.

Although third parties may offer a license to their technology or other intellectual property, the terms of any offered license may not be
acceptable and the failure to obtain a license or the costs associated with any license could materially and adversely affect our business, financial condition, and operating results. If a third-party does not offer us a license to its technology or
other intellectual property on reasonable terms, we could be enjoined from continued use of such intellectual property. As a result, we may be required to develop alternative, non-infringing technology, which could require significant time (during
which we would be unable to continue to offer our affected products or services), effort and expense and may ultimately not be successful.

We may
acquire or make investments in other businesses which could require significant management attention, disrupt our business, dilute stockholder value and adversely affect our operating results.

As part of our business strategy, we have in the past and we may in the future acquire or make investments in complementary companies,
products or technologies. We cannot assure you that we will realize the anticipated benefits of these or any future acquisitions. The pursuit of potential acquisitions may divert the attention of management and cause us to incur various expenses in
identifying, investigating and pursuing suitable acquisitions, whether or not they are consummated. We may not be able to find suitable acquisition candidates, or we may not be able to complete such acquisitions on favorable terms. If we do complete
acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, and any acquisitions we complete could be viewed negatively by our customers, investors and securities analysts. In addition, if we are unsuccessful at
integrating such acquisitions, or the technologies associated with such acquisitions, into our company, our operating results could be adversely affected. We may also incur unforeseen liabilities which could materially and adversely affect our
operating results. We may not successfully evaluate or utilize the acquired technology or personnel or accurately forecast the financial impact of an acquisition transaction, including accounting charges. The sale of equity or issuance of debt to
finance any such acquisitions could result in dilution to our stockholders. The incurrence of indebtedness would result in increased fixed obligations and could also include covenants or other restrictions that would impede our ability to manage our
operations.

Our failure to raise additional capital or generate the significant capital necessary to expand our operations and invest in new
features and apps could reduce our ability to compete and could harm our business.

We may need to raise additional funds in the
future, and we may not be able to obtain additional debt or equity financing on favorable terms, if at all. If we raise additional equity financing, our stockholders may experience significant dilution of their ownership interests, and the per share
value of our common stock could decline. Furthermore, if we engage in debt financing, the holders of debt would have priority over the holders of common stock, and we may be required to accept terms that restrict our ability to incur additional
indebtedness. We may also be required to take other actions that would otherwise be in the interests of the debt holders or to maintain specified liquidity or other ratios, any of which could harm our business, operating results and financial

condition. If we need additional capital and cannot raise it on acceptable terms, we may not be able to, among other things:



develop or enhance our platform;



make marketing expenditures to acquire new members and subscribers;



continue to expand our marketing and research and development organizations;



acquire complementary companies, products or technologies;



expand our operations;



hire, train and retain employees; or



respond to competitive pressures or unanticipated working capital requirements.

Our failure
to do any of these things could seriously harm our business, financial condition and operating results.

Adverse economic conditions may affect our
business.

Our performance is subject to economic conditions and their impact on levels of spending by members and subscribers,
which may be disproportionately affected by economic downturns. To the extent that economic conditions materially deteriorate, our renewal and conversion rates may decline. Economic conditions may adversely affect levels of consumer discretionary
spending, which could adversely affect the numbers of members subscribing to our platform. Consumer purchases of discretionary items generally decline during recessionary periods and other periods in which disposable income is adversely affected,
which could have a material adverse effect on our financial condition and results of operations.

Our management team has limited experience
managing a public company.

Our management team has limited experience managing a publicly-traded company, interacting with public
company investors and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition to being a public company subject to significant regulatory oversight
and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents will require significant attention from our senior management and could divert their
attention away from the day-to-day management of our business, which could adversely affect our business, financial condition and operating results.

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and
accurate financial statements or comply with applicable regulations could be impaired.

As a public company, we will be subject to
the reporting requirements of the Securities Exchange Act of 1934, as amended (the Exchange Act), the Sarbanes-Oxley Act of 2002 (the Sarbanes-Oxley Act) and the rules and regulations of the applicable listing standards of
the New York Stock Exchange (NYSE). We expect that the requirements of these rules and regulations will continue to increase our legal, accounting and financial compliance costs, make some activities more difficult, time-consuming and
costly and place significant strain on our personnel, systems and resources.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure
controls and procedures and internal control over financial reporting. We are continuing to develop and refine our disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports
that we will file with the Securities and Exchange Commission (the SEC) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and that information required to be disclosed in reports
under the Exchange Act is accumulated and communicated to our principal executive and financial officers. We are also continuing to improve our internal control over financial reporting. In order to maintain and improve the effectiveness of our
disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will continue to expend, significant resources, including accounting-related costs and significant management oversight.

Our current controls and any new controls that we develop may become inadequate because of changes in conditions in our business. Further,
weaknesses in our disclosure controls and internal control over financial reporting may be discovered in the future. Any failure to develop or maintain effective controls or any difficulties encountered in their implementation or improvement could
harm our operating results or cause us to fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods. Any failure to implement and maintain effective internal control over financial reporting
also could adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting that we will
eventually be required to include in our periodic reports that will be filed with the SEC. Ineffective disclosure controls and procedures and internal control over financial reporting could also cause investors to lose confidence in our reported
financial and other information, which would likely have a negative effect on the trading price of our common stock. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on the NYSE. We are not
currently required to comply with the SEC rules that implement Section 404 of the Sarbanes-Oxley Act and are therefore not required to make a formal assessment of the effectiveness of our internal control over financial reporting for that
purpose. As a public company, we will be required to provide an annual management report on the effectiveness of our internal control over financial reporting commencing with our second annual report on Form 10-K.

Our independent registered public accounting firm is not required to formally attest to the effectiveness of our internal control over
financial reporting until after we are no longer an emerging growth company as defined in the JOBS Act. At such time, our independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied
with the level at which our internal control over financial reporting is documented, designed or operating. Any failure to maintain effective disclosure controls and internal control over financial reporting could have a material and adverse effect
on our business and operating results and could cause a decline in the price of our common stock.

Our business depends on members continued
and unimpeded access to our platform on the Internet and the development and maintenance of Internet infrastructure.

The adoption
of any laws or regulations that adversely affect the growth, popularity or use of the Internet, including laws impacting Internet neutrality, could decrease the demand for our solution and increase our operating costs. For example, in late 2010, the
FCC adopted rules intended, in part, to maintain net neutrality and to prevent network operators from discriminating against legal traffic that transverse their networks. Recently, the U.S. Court of Appeals for the District of Columbia struck down
these net neutrality rules and it is currently uncertain how the FCC will respond to this decision. To the extent network operators attempt to use this ruling to extract fees from us to deliver our solution or otherwise engage in discriminatory
practices, our business could be adversely impacted. Internationally, government regulation concerning the Internet, and in particular, network neutrality, may be developing or non-existent. Within such a regulatory environment, we could experience
discriminatory or anti-competitive practices that could impede our domestic and international growth, cause us to incur additional expense or otherwise negatively affect our business. Furthermore, from time to time, network operators and the
Internet have experienced, and are likely to continue to experience, a variety of

outages and other delays as a result of damage to portions of Internet infrastructure. The failure of network operators or Internet infrastructure that we and our members rely on, even for a
short period of time, could undermine our operations and harm our operating results.

Our business is subject to the risks of earthquakes, fires,
floods and other natural catastrophic events and to interruption by man-made problems such as computer viruses or terrorism.

Our
systems and operations are vulnerable to damage or interruption from earthquakes, fires, floods, power losses, telecommunications failures, terrorist attacks, acts of war, human errors, cyberattacks, break-ins and similar events. The third-party
systems and operations we rely on, such as the data centers we lease, are subject to similar risks. For example, a significant natural disaster, such as an earthquake, fire or flood, could have a material adverse impact on our business, operating
results and financial condition, and our insurance coverage may be insufficient to compensate us for losses that may occur. Our corporate offices and certain development servers are located in the San Francisco Bay Area, a region known for seismic
activity. In addition, acts of terrorism, which may be targeted at metropolitan areas such as San Francisco, could cause disruptions in our business or the economy as a whole. The servers we rely on may also be vulnerable to cyberattacks, computer
viruses, break-ins and similar disruptions from unauthorized tampering with computer systems, as well as to software bugs and hardware or network failures, any of which could lead to interruptions, delays, loss of critical data or the unauthorized
disclosure of confidential member data. We may not have sufficient protection or recovery plans in some circumstances, such as natural disasters affecting the San Francisco Bay Area. As we rely heavily on data centers, computer and communications
systems and the Internet to conduct our business and provide high-quality customer service, such disruptions could negatively impact our ability to run our business, which could have a material adverse effect on our business, operating results and
financial condition.

Our ability to use net operating losses to offset future taxable income may be subject to certain limitations.

As of December 31, 2013, we had federal and state net operating loss (NOLs) carryforwards of $81.6 million and
$74.8 million, respectively, due to prior period losses. If not utilized, the federal and state NOLs will begin to expire in 2027 and 2017, respectively. If these NOLs expire unused and are unavailable to offset future taxable income, our
profitability may be adversely affected. In addition, under Section 382 of the U.S. Internal Revenue Code of 1986 (the Code), a corporation that undergoes an ownership change is subject to limitations on its ability to
utilize its pre-change NOLs to offset future taxable income. We believe we have undergone one or more ownership changes in the past and that as a result a portion of our NOLs may be subject to certain limitations. If we have undergone other
ownership changes or if we undergo an ownership change in connection with this offering or otherwise in the future, our ability to utilize our NOLs could be further limited by Section 382 of the Code. Future changes in our stock ownership may
be outside of our control. Our NOLs could also be impaired under state law. As a result, we might not be able to utilize a material portion of our NOLs to offset future tax liabilities.

We are an emerging growth company and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies
will make our common stock less attractive to investors.

We are an emerging growth company, as defined in the JOBS
Act, and we intend to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including not being required to comply with the auditor
attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding
advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. We may take advantage of these exemptions for so long as we are an emerging growth company, which could be as long
as five years following the completion of this offering. We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there
may be a less active trading market for our common stock and our stock price may be more volatile.

Risks Related to This Offering, the Securities Markets and Ownership of Our Common Stock

There has been no prior public market for our common stock, the stock price of our common stock may be volatile or may decline regardless of our
operating performance and you may not be able to resell your shares at or above the initial public offering price.

There has been
no public market for our common stock prior to this offering. The initial public offering price for our common stock will be determined through negotiations between the underwriters and us and may vary from the market price of our common stock
following this offering. If you purchase shares of our common stock in this offering, you may not be able to resell those shares at or above the initial public offering price. An active or liquid market in our common stock may not develop following
this offering or, if it does develop, may not be sustainable. The market price of our common stock may fluctuate significantly in response to numerous factors, many of which are beyond our control, including:



overall performance of the equity markets;



our operating performance and the performance of other similar companies;



changes in the estimates of our operating results that we provide to the public, our failure to meet these projections or changes in recommendations by securities analysts that elect to follow our common stock;



announcements of technological innovations, new apps or enhancements to services, acquisitions, strategic alliances or significant agreements by us or by our competitors;



recruitment or departure of key personnel;



the economy as a whole and market conditions in our industry;



the expiration of contractual lock-up or market standoff agreements;



the size of our market float; and



any other factors discussed in this prospectus.

In addition, the stock markets have
experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many technology companies. Stock prices of many technology companies have fluctuated in a manner unrelated or
disproportionate to the operating performance of those companies. In the past, stockholders have filed securities class action litigation following periods of market volatility. If we were to become involved in securities litigation, it could
subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business.

Substantial
blocks of our total outstanding shares may be sold into the market when lock-up or market standoff periods end. If there are substantial sales of shares of our common stock, the price of our common stock could decline.

The price of our common stock could decline if there are substantial sales of our common stock, particularly sales by our directors, executive
officers and principal stockholders or if there is a large number of shares of our common stock available for sale. Substantially all of our securities outstanding prior to this offering are currently restricted from resale as a result of lock-up
and market standoff agreements, as described in greater detail below in the section titled Shares Eligible for Future Sale. These shares will become available to be sold

181 days after the date of this prospectus. Shares held by directors, executive officers and other affiliates will be subject to volume limitations under Rule 144 under the Securities Act of
1933, as amended, and various vesting agreements.

After this offering, certain of our stockholders will have rights, subject to some
conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or our stockholders. All of these shares are subject to lock-up or market standoff
agreements restricting their sale until 181 days after the date of this prospectus. We also intend to register shares of common stock that we have issued and may issue under our stock-based compensation plans. Once we register these shares, they
will be able to be sold freely in the public market upon issuance, subject to existing lock-up or market standoff agreements.

The market price of the shares of our common stock could decline as a result of the sale of a substantial number of our shares of common stock
in the public market or the perception in the market that the holders of a large number of shares intend to sell their shares.

Because the initial
public offering price of our common stock will be substantially higher than the pro forma net tangible book value per share of our outstanding common stock following this offering, new investors will experience immediate and substantial dilution.

The initial public offering price is substantially higher than the pro forma net tangible book value per share of our common
stock immediately following this offering based on the total value of our tangible assets less our total liabilities. Therefore, if you purchase shares of our common stock in this offering, based on the midpoint of the price range set forth on the
cover of this prospectus, and the issuance of shares of common stock in this offering, you will experience immediate
dilution of $ per share, the difference between the price per share you pay for our common stock and its pro forma net tangible book value per share immediately following this offering as of
December 31, 2013.

If securities and industry analysts do not publish research or publish inaccurate or unfavorable research about our
business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the
research and reports that securities and industry analysts publish about us or our business. If few analysts commence coverage of us or if analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could
decrease, which might cause our common stock price and trading volume to decline. If one or more of the analysts who cover us downgrade our common stock or publish inaccurate or unfavorable research about our business, our common stock price could
decline.

We have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

We have broad discretion in the application of the net proceeds from this offering. Possible uses include marketing activities, working
capital, acquisitions and other general corporate purposes, and we may spend or invest these proceeds in a way with which our stockholders disagree. The failure by our management to apply these funds effectively could adversely affect our business
and operating results. Pending their use, we may invest the net proceeds from this offering in a manner that does not produce income or that loses value. These investments may not yield a favorable return to our investors.

Our directors, executive officers and principal stockholders will continue to have substantial control over
us after this offering and could delay or prevent a change in corporate control.

After this offering, our directors, executive
officers and holders of more than 5% of our common stock, together with their affiliates, will beneficially own, in the aggregate, % of our outstanding common stock, based on the midpoint of the price range set forth on the
cover of this prospectus and the issuance of shares in this offering. As a result, these stockholders, acting together, would have the ability to control the outcome of
matters submitted to our stockholders for approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets. In addition, these stockholders, acting together, would have the ability to
control the management and affairs of our company. Accordingly, this concentration of ownership could harm the market price of our common stock by:



delaying, deterring or preventing a change in control of us;



impeding a merger, consolidation, takeover or other business combination involving us; or



discouraging a potential acquiror from making a tender offer or otherwise attempting to obtain control of us.

See Principal Stockholders for more information regarding the beneficial ownership of our outstanding capital stock by our
directors, executive officers and principal stockholders.

We do not intend to pay dividends for the foreseeable future.

We have never declared nor paid cash dividends on our capital stock. We currently intend to retain any future earnings to finance the
operation and expansion of our business, and we do not expect to declare or pay any dividends in the foreseeable future. Consequently, stockholders must rely on sales of their common stock after price appreciation, which may never occur, as the only
way to realize any future gains on their investment.

Delaware law and provisions in our amended and restated certificate of incorporation and
amended and restated bylaws could make a merger, tender offer or proxy contest difficult.

Upon completion of this offering, our
status as a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law may discourage, delay or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder
for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our existing stockholders. In addition, our amended and restated certificate of incorporation and amended and restated
bylaws that will be in effect upon completion of this offering will contain the following provisions:



our board of directors will be classified into three classes of directors with staggered three-year terms, and directors will only be able to be removed from office for cause;



only our board of directors will have the right to fill a vacancy created by the expansion of our board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to
fill vacancies on our board of directors;



only our chairman of the board, our chief executive officer, our president, or a majority of our board of directors will be authorized to call a special meeting of stockholders;

our amended and restated certificate of incorporation will authorize undesignated preferred stock, the terms of which may be established, and shares of which may be issued, without the approval of the holders of common
stock; and



advance notice procedures will apply for stockholders to nominate candidates for election as directors or to bring matters before an annual meeting of stockholders.

These provisions, which are described in greater detail below in the section titled Description of Capital Stock, may make the
acquisition of our company more difficult, and could in turn limit the opportunity for our stockholders to receive a premium for their shares of our common stock.

This prospectus, including the sections entitled Prospectus Summary, Risk Factors, Use of Proceeds,
Managements Discussion and Analysis of Financial Condition and Results of Operations and Business, contains forward-looking statements. All statements contained in this prospectus other than statements of historical
fact, including statements regarding our future results of operations or financial condition, our business strategy and plans and our objectives for future operations, are forward-looking statements. The words believe, may,
will, potentially, estimate, continue, anticipate, intend, could, would, project, plan, expect and similar
expressions that convey future events or outcomes are intended to identify forward-looking statements.

These forward-looking statements
are subject to a number of risks, uncertainties and assumptions, including those described in Risk Factors and elsewhere in this prospectus. Moreover, we operate in a very competitive and rapidly changing environment, and new risks
emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ
materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties, and assumptions, the forward-looking events and circumstances discussed in this prospectus may not occur and actual results could
differ materially and adversely from those anticipated or implied in the forward-looking statements.

You should not rely upon
forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, levels of activity, performance or events
and circumstances reflected in the forward-looking statements will be achieved or occur. We undertake no obligation to update publicly any forward-looking statements for any reason after the date of this prospectus to conform these statements to new
information, actual results or to changes in our expectations, except as required by law.

You should read this prospectus and the
documents that we reference in this prospectus and have filed with the SEC as exhibits to the registration statement of which this prospectus is a part with the understanding that our actual future results, levels of activity, performance and
events and circumstances may be materially different from what we expect.

Unless otherwise indicated, information contained in this prospectus concerning our industry and the markets in which we operate, including
our general expectations and market position, market opportunity, and market size, is based on information from various sources, on assumptions that we have made that are based on those data and other similar sources and on our knowledge of the
markets for our solution. This information involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions and estimates of our future performance and the
future performance of the industry in which we operate is necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in Risk Factors and elsewhere in this prospectus. These and
other factors could cause results to differ materially from those expressed in the estimates made by the independent parties and by us.

Certain information in the text of the prospectus is contained in independent scholarly, industry or governmental publications or reports. The
source of, and selected additional information contained in, these independent scholarly, industry or governmental publications or reports are provided below:

The numbers of members and subscribers presented in this prospectus are based on internal company data. While these numbers are based on what
we believe to be reasonable measures of our member and subscriber base for the applicable balance sheet date, there are challenges in measuring certain metrics. For example, historically, we did not record our number of members at each balance sheet
date. Accordingly, we calculated our number of members in this prospectus as of December 31, 2010, 2011, 2012 and 2013 using reports that were generated from our system in January 2014. However, due to historical system limitations, these
reports exclude from our number of members those members whose profiles were deactivated between the balance sheet date and January 2014. Accordingly, the number of members reported for past dates may be understated as compared to the number that
would have resulted if we had run the report as of the balance sheet date due to subsequent deactivations, which may imply higher growth rates than what actually occurred. In the future, we intend to calculate our number of members using reports
generated on each balance sheet date. In December 2010, we refined our methodology for tracking the long-term engagement of our subscribers, as presented in Managements Discussion and Analysis of Financial Condition and Results of
OperationsSubscriber Analysis. Due to system limitations, we are unable to apply the refined methodology to prior periods. Accordingly, actual rates of long-term engagement for our pre-2011 subscriber cohorts may differ from those
presented. We regularly review and may adjust our processes for calculating our operating metrics to improve their accuracy.

We estimate that the net proceeds from our sale of
shares of common stock in this offering at an assumed initial public offering price of
$ per share, the midpoint of the price range set forth on the cover page of this prospectus, after deducting estimated underwriting discounts and commissions and estimated offering expenses
payable by us, will be approximately $ million, or $ million if the underwriters exercise their option to purchase additional shares in full. A
$1.00 increase (decrease) in the assumed initial public offering price would increase (decrease) the net proceeds to us from this offering by $ million, assuming the number of shares offered by us
remains the same and after deducting estimated underwriting discounts and commissions.

The principal purposes of this offering are to
increase our financial flexibility, create a public market for our common stock and thereby enable future access to the public equity markets by us and our stockholders, obtain additional capital and increase our visibility in the marketplace. We
currently intend to use the net proceeds that we receive from this offering primarily for general corporate purposes, which may include marketing activities, working capital, product development, general and administrative matters and capital
expenditures. We may also use a portion of the net proceeds for the acquisition of, or investment in, technologies, solutions or businesses that complement our business. However, we currently have no agreements or commitments with respect to any
specific acquisitions or investments. We will have broad discretion over the uses of the net proceeds of this offering.

Pending these
uses, we intend to invest the net proceeds from this offering in short-term, investment-grade interest-bearing securities such as money market accounts, certificates of deposit, commercial paper and guaranteed obligations of the
U.S. government.

DIVIDEND POLICY

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all available funds and any future earnings
for use in the operation of our business and do not anticipate paying any dividends on our common stock in the foreseeable future. Any future determination to declare dividends will be made at the discretion of our board of directors and will depend
on our financial condition, operating results, capital requirements, general business conditions and other factors that our board of directors may deem relevant. In addition, the terms of our credit facility contains restrictions on our ability to
pay dividends.

The following table sets forth our cash and cash equivalents and capitalization as of December 31, 2013 on:



an actual basis;



a pro forma basis, giving effect to (i) the automatic conversion of all outstanding shares of our convertible preferred stock into an aggregate of 31,822,227 shares of common stock, (ii) the resulting
reclassification of the preferred stock warrant liability from other long-term liabilities to additional paid-in capital and (iii) the effectiveness of our amended and restated certificate of incorporation in connection with the completion of
this offering; and



a pro forma as adjusted basis, giving effect to the pro forma adjustments set forth above and: (i) the exercise of an outstanding warrant for an aggregate of 31,852 shares of our common stock on or prior to the
completion of this offering and (ii) the sale of shares of common stock by us in this offering, based on an assumed initial
public offering price of $ per share, the midpoint of the price range set forth on the cover page of this prospectus, after deducting the estimated underwriting discounts and commissions and estimated
offering expenses payable by us.

The pro forma as adjusted information set forth in the table below is illustrative only
and will be adjusted based on the actual initial public offering price and other terms of this offering determined at pricing.

You
should read this table together with Managements Discussion and Analysis of Financial Condition and Results of Operations and our consolidated financial statements and related notes included elsewhere in this prospectus.

Each $1.00 increase (decrease) in the assumed initial public offering price of $ per share, the midpoint of the price range set forth on the cover page of this prospectus,
would increase (decrease) our pro forma as adjusted cash and cash equivalents, additional paid-in capital, total stockholders (deficit) equity and total capitalization by approximately $ million,
assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated underwriting discounts and commissions.

The number of shares of our common stock to be outstanding after this offering is based on 46,352,452 shares of our common stock outstanding
as of December 31, 2013, and excludes:



7,133,825 shares of common stock issuable upon the exercise of options outstanding as of December 31, 2013, with a weighted-average exercise price of $2.72 per share;



511,970 shares of common stock issuable upon the exercise of warrants outstanding as of December 31, 2013, with a weighted-average exercise price of $1.84 per share;



4,801,250 shares of common stock issuable upon the exercise of options granted between December 31, 2013 and April 17, 2014, with a weighted-average exercise price of $5.94 per share; and



12,265,724 shares of common stock reserved for future issuance under our equity compensation plans as of December 31, 2013, consisting of (a) 3,765,724 shares of common stock reserved for future issuance under
our 2007 Stock Plan (which reserve: (i) includes the options to purchase shares of our common stock granted after December 31, 2013 and (ii) excludes an increase to the reserve of 2,000,000 shares of our common stock in February
2014), (b) 7,000,000 shares of common stock reserved for future issuance under our 2014 Equity Incentive Plan, which will become effective in connection with the completion of this offering (which reserve includes the options to purchase shares
of our common stock granted to our non-employee directors on the date of this prospectus), and (c) 1,500,000 shares of common stock reserved for future issuance under our 2014 Employee Stock Purchase Plan, which will become effective in
connection with the completion of this offering. In connection with the completion of this offering, any remaining shares available for issuance under our 2007 Stock Plan will be added to the shares reserved under our 2014 Equity Incentive Plan, and
we will cease granting awards under our 2007 Stock Plan. Our 2014 Equity Incentive Plan and 2014 Employee Stock Purchase Plan also provide for automatic annual increases in the number of shares reserved under the plans each year, as more fully
described in Executive CompensationEmployee Benefit and Stock Plans.

If you invest in our common stock in this offering, your interest will be diluted to the extent of the difference between the initial public
offering price and the pro forma as adjusted net tangible book value per share of our common stock immediately after this offering.

As of December 31, 2013, our pro forma net tangible book value was $ million, or
$ per share of common stock. Our pro forma net tangible book value per share represents the amount of our total tangible assets reduced by the amount of our total liabilities and divided by the total
number of shares of our common stock outstanding as of December 31, 2013, assuming the conversion of all outstanding shares of our convertible preferred stock into common stock and the resulting reclassification of the preferred stock warrant
liability from other long-term liabilities to additional paid-in capital in connection with this offering.

After giving effect to the pro
forma adjustments set forth above and: (i) the exercise of an outstanding warrant for an aggregate of 31,852 shares of our common stock on or prior to the completion of this offering and (ii) our sale in this offering of
shares of our common stock, at an assumed initial public offering price of $ per
share, the midpoint of the price range set forth on the cover page of this prospectus, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value
as of December 31, 2013 would have been $ million, or $ per share of our common stock. This represents an immediate increase in pro forma net
tangible book value of $ per share to our existing stockholders and an immediate dilution of $ per share to investors purchasing shares in this offering
as follows:

Assumed initial public offering price per share

$

Pro forma net tangible book value per share as of December 31, 2013

$

Increase in pro forma net tangible book value per share attributable to new investors purchasing shares in this offering

Pro forma as adjusted net tangible book value per share after this offering

Dilution in pro forma net tangible book value per share to investors in this offering

$

A $1.00 increase (decrease) in the assumed initial public offering price of
$ per share, the midpoint of the price range set forth on the cover page of this prospectus, would increase (decrease) our pro forma as adjusted net tangible book value by
$ per share, and the dilution in pro forma net tangible book value per share to investors in this offering by $ per share, assuming the number of shares
offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions. Similarly, each increase (decrease) of 1,000,000 shares in the number of shares of common stock
offered by us would increase (decrease) the pro forma as adjusted net tangible book value by $ per share and increase (decrease) the dilution to new investors by
$ per share, assuming the assumed initial public offering price remains the same and after deducting the estimated underwriting discounts and commissions.

If the underwriters exercise their option to purchase additional shares in full at the assumed initial public offering price, the pro forma as
adjusted net tangible book value per share of our common stock would be $ per share, and the dilution in pro forma net tangible book value per share to investors in this offering would be
$ per share.

The following table summarizes as of December 31, 2013, on a pro forma as adjusted basis as
described above, the difference between existing stockholders and new investors with respect to the number of shares of common stock purchased from us, the total consideration paid to us and the average price per share paid, before deducting
estimated underwriting discounts and commissions and estimated offering expenses payable by us:

A $1.00 increase (decrease) in the assumed initial public offering price of
$ per share, the midpoint of the price range set forth on the cover page of this prospectus, would increase (decrease) total consideration paid by new investors and total consideration paid by all
stockholders by approximately $ million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting the estimated
underwriting discounts and commissions.

To the extent that any outstanding options are exercised, investors will experience further
dilution.

Except as otherwise indicated, the above discussion and tables assume no exercise of the underwriters option to purchase
additional shares. If the underwriters exercise their option to purchase additional shares in full, our existing stockholders would own % and our new investors would own % of the total number of shares
of our common stock outstanding upon the completion of this offering.

The number of shares of our common stock to be outstanding after
this offering is based on 46,352,452 shares of our common stock outstanding as of December 31, 2013, and excludes:



7,133,825 shares of common stock issuable upon the exercise of options outstanding as of December 31, 2013, with a weighted-average exercise price of $2.72 per share;



511,970 shares of common stock issuable upon the exercise of warrants outstanding as of December 31, 2013, with a weighted-average exercise price of $1.84 per share;



4,801,250 shares of common stock issuable upon the exercise of options granted between December 31, 2013 and April 17, 2014, with a weighted-average exercise price of $5.94 per share; and



12,265,724 shares of common stock reserved for future issuance under our equity compensation plans as of December 31, 2013, consisting of
(a) 3,765,724 shares of common stock reserved for future issuance under our 2007 Stock Plan (which reserve: (i) includes the options to purchase shares of our common stock granted after December 31, 2013 and (ii) excludes an
increase to the reserve of 2,000,000 shares of our common stock in February 2014), (b) 7,000,000 shares of common stock reserved for future issuance under our 2014 Equity Incentive Plan, which will become effective in connection with the
completion of this offering (which reserve includes the options to purchase shares of our common stock granted to our non-employee directors on the date of this prospectus), and (c) 1,500,000 shares of common stock reserved for future issuance
under our 2014 Employee Stock Purchase Plan, which will become effective in connection with the completion of this offering. In connection with the completion of this offering, any remaining shares available for issuance under our 2007 Stock Plan
will be added to the shares reserved under

our 2014 Equity Incentive Plan, and we will cease granting awards under our 2007 Stock Plan. Our 2014 Equity Incentive Plan and 2014 Employee Stock Purchase Plan also provide for automatic annual
increases in the number of shares reserved under the plans each year, as more fully described in Executive CompensationEmployee Benefit and Stock Plans.

Members access our platform through Zoosk.com and mobile and social media apps. We primarily generate revenues from subscriptions and offer one-,three- and six-month subscription plans. Members are able to create a full profile and view other members profiles.
Subscribers have full access to our communication platform and certain premium features. We also generate revenues from virtual currency, which can be redeemed for other premium features such as Boost, virtual gifts and special delivery of messages.

Zoosk is a global brand, serving a global member base with one platform from one location. For 2012 and 2013, the percentage of total
revenues from international members was 51% and 49%, respectively. Our member base has grown organically rather than through acquisitions. We believe there is a large and growing global opportunity, and we intend to continue to scale our investments
in marketing and focus our efforts on the acquisition of new members and subscribers in both existing and new markets.

Our number of members grew from over 18 million as of December 31, 2012 to over
26 million as of December 31, 2013. During the same period, our number of subscribers grew from approximately 483,000 to approximately 650,000. Our total revenues grew by 63% from $109.1 million to $178.2 million in 2012 and 2013,
respectively. We had net losses of $20.7 million and $2.6 million in 2012 and 2013, respectively.

Key Metrics

In addition to our consolidated financial statements, we regularly review certain metrics, including the following key metrics, to evaluate
our business, measure our performance, identify trends in our business, prepare operating plans and make strategic decisions. We believe the information obtained from the review of these metrics is useful for investors to understand the underlying
trends in our business. The following table presents our key metrics:

Members. We define a member as a person with a profile that includes a validated email
address, a photograph and certain other attributes, such as age and location, and whose profile has not been deactivated (but which may include a member whose profile has not had recent activity), as of the date of measurement. The number of members
is a key indicator of our scale, which leads to increased value for our members.

Due to the episodic nature of dating, many
of our members reengage with our platform multiple times during their dating life. Members who have not recently used our platform typically continue to receive notifications from us of potential connections or interest by other members in their
profiles and may choose to reengage with our platform based on such notifications. Our Behavioral Matchmaking engine generally prioritizes the display of profiles of members who are more active higher in displays of potential connections, although
we do not specifically monitor the number of profiles that have not had recent activity.

Subscribers. We define a
subscriber as a member with a paid subscription as of the date of measurement. The number of subscribers increased 35% as of December 31, 2013 as compared to December 31, 2012 and 53% as of December 31, 2012 as compared to
December 31, 2011.

The numbers of members and subscribers presented in this prospectus are based on internal company
data. While these numbers are based on what we believe to be reasonable measures of our member and subscriber base for the applicable balance sheet date, there are challenges in measuring certain metrics. For example, historically, we did not record
our number of members at each balance sheet date. Accordingly, we calculated our number of members in this prospectus as of December 31, 2010, 2011, 2012 and 2013 using reports that were generated from our system in January 2014, which excludes
members who deactivated between these balance sheet dates and the report date. For additional detail regarding certain limitations on our member and subscriber metrics, see Industry Data and Company Metrics.

Subscriber Analysis

It is important
that we attract new members and subscribers to our platform. The primary way we attract new members and subscribers is through the purchase of advertising. Advertising spend consists of media purchases, which includes display, mobile, television,
social and search channels, and excludes public relations spend, fees paid to third-party platform providers and personnel-related expenses. We measure return on advertising as the bookings from a subscriber cohort, which we define as all members
who subscribe for the first time in a particular period, as measured against the advertising spend during the same period. We define bookings from a subscriber cohort as all subscription and virtual currency purchases made by that cohort in a

period. In 2012 and 2013, for a substantial majority of our monthly subscriber cohorts, bookings from the cohort surpassed the corresponding advertising spend within seven months. We cannot
guarantee that this pattern is indicative of future cohorts or will be sustained in the future.

It is also important that we retain our
members and subscribers on our platform. Due to the episodic nature of dating, many of our members subscribe multiple times during their dating life. In any given year, there is a certain percentage of subscribers who contribute to total revenues in
a year subsequent to the year in which they initially subscribed, who we refer to as returning subscribers. Returning subscribers consist of (1) subscribers who cancel their subscription and later return to our platform as a subscriber,
(2) subscribers who consecutively renew their subscription and (3) subscribers with a subscription that starts in one year and carries over into the subsequent year. The following table illustrates the percentage of subscribers from our
2008, 2009, 2010, 2011 and 2012 annual subscriber cohorts who were returning subscribers in 2013. For example, 6% of our 2008 subscriber cohort were returning subscribers, five years later, in 2013.

Factors Affecting Our Performance

We believe that our performance and future success depend upon a number of factors, including:

Advertising spend. Our advertising spend, which is included in our marketing expense, has consistently been
our largest operating expense. In recent periods, we have focused our adverting spend on display, mobile, television, social and search channels. We seek to optimize for total return on advertising spend by frequently analyzing and adjusting this
spend through numerous campaigns to focus on the channels and markets that generate a high return. Our data-driven approach provides us the flexibility to scale and optimize our advertising spend. Our operating results may be impacted if the timing,
size, number or effectiveness of our advertising campaigns is miscalculated or if these campaigns are inefficient.

International markets. Our platform is available in 80 countries. As of December 31, 2013, 62% of our
member base consisted of international members. In 2013, 49% of our total revenues were international. We vary our pricing to align with local market conditions. Our results may be impacted by changes in local economic conditions. Because the vast
majority of our expenses are denominated in U.S. dollars, our future results may also be affected by currency exchange rates.

Mobile platform. We believe the use of mobile devices will continue to increase, and that our ability to compete for, and
engage, members and subscribers will depend on our ability to continue to enhance our

platform, particularly for mobile features. In 2013, 41% of first-time subscribers paid through a mobile device, up from 22% in 2012.

Basis of Presentation

Revenues

We derive our revenues from subscriptions and virtual currency.

Subscription. We primarily generate revenues from subscriptions. We offer our members one-, three- and six-month subscription
plans which typically automatically renew. For 2011, 2012 and 2013, our subscription plans bytotal bookings were as follows: 62%, 62% and 63% one-month; 19%, 17% and 15% three-month; and 19%, 21% and 22% six-month, respectively. In
2011, 2012 and 2013, 52%, 52% and 51%, respectively, of our total bookings came from repeat subscribers, who we define as subscribers who cancel their subscription and later return to our platform as a subscriber, and subscribers who consecutively
renew their subscription. Total bookings are defined as total revenues recognized in a period plus the change in deferred revenue during the period. Subscriptions are paid upfront and are recorded as deferred revenue at the time of purchase and
recognized as revenues ratably, on a daily basis over the applicable subscription period.

Virtual
currency. Sales of virtual currency are recorded as deferred revenue at the time of purchase and recognized as revenues as the virtual currency is redeemed.

Cost of revenues

Our cost of
revenues primarily consists of service fees related to the review of text and photo content, payment processor fees and web hosting. It also includes depreciation expense related to operating our data centers as well as personnel-related expenses,
which primarily consist of salary, bonus and stock-based compensation, for our member operations teams. We expect cost of revenues to increase in future periods.

Operating expenses

We classify
our operating expenses into three categories: marketing, research and development, and general and administrative.

Marketing.
Our marketing expenses primarily consist of advertising spend, fees paid to third-party platform providers and public relations, as well as personnel-related expenses. We plan to continue to invest in marketing to grow our global member and
subscriber base and continue building brand awareness. As a result, we expect marketing expenses to increase and continue to be our largest expense.

Research and development. Our research and development expenses primarily consist of personnel-related expenses for our
engineers, product managers, designers and consulting fees. We believe that continued investment in enhancements to our solution such as adding new features, improving our mobile platform and further localizing our solution for international markets
is important for attracting and retaining members. As a result, we expect research and development expenses to increase in future periods.

General and administrative. Our general and administrative expenses primarily consist of personnel-related expenses for our
executive team, finance, human resources, legal, other administrative employees andprofessional fees. We expect that our general and administrative expenses will increase as we continue to expand our business and incur additional
expenses associated with being a public company.

Other expense, net

Other expense, net primarily consists of interest expense related to our loan facility, foreign exchange gain and loss and changes in the fair
value of our preferred stock warrants. Upon the completion of this offering,

our convertible preferred stock warrants will convert into common stock warrants and we will no longer incur expense related to changes in the fair value of these warrants.

We intend to continue to make significant investments in our marketing activities to focus on member and subscriber
acquisition, and to a lesser extent, we intend to continue to make investments in research and development and general and administrative expenses in order to enhance our solution and invest in infrastructure needed as a public
company. In light of our growth strategy, we expect that our total cost of revenues and operating expenses will continue to increase, which will limit our ability to achieve or maintain profitability in the foreseeable future.

Results of Operations

The following
table sets forth our consolidated statements of operations data for the periods shown:

2012 compared to 2013. Total revenues increased $69.1 million, or 63%, in 2013 as
compared to 2012. Revenues from subscriptions increased $50.1 million, or 48%, primarily as a result of an increase in the number of subscribers. The number of subscribers as of December 31, 2013 was approximately 650,000 compared toapproximately 483,000 as of December 31, 2012. This increase coincided with an increase of $31.0 million in advertising spend, primarily related to online advertising, in 2013 as compared to 2012. Additionally, in the second half of
2012, we released our enhanced mobile apps, which accounted for 41% of first time subscriptionpurchases in 2013. Revenues from virtual currency increased $19.0 million, or 353%, primarily due to premium features introduced in the
second half of 2012 that require the redemption of virtual currency. U.S. revenues increased $38.1 million in 2013 as compared to 2012 and international revenues increased $31.0 million for the same period.

2011 compared to 2012. Total revenues increased $11.9 million, or 12%, in 2012 as compared to 2011. Revenues from subscriptions
increased $9.3 million, or 10%, primarily as a result of an increase in the number of subscribers. The number of subscribers as of December 31, 2012 was approximately 483,000 compared to approximately 316,000 as of December 31, 2011. The
increase in subscribers primarily occurred in the second half of 2012, which coincided with an increase in advertising spend in the same period. Revenues from virtual currency increased $2.6 million, or 96%, primarily due to the release during the
second half of 2012 of new premium features that require the redemption of virtual currency. U.S. revenues increased $2.5 million in 2012 as compared to 2011 and international revenues increased $9.4 million for the same period.

2012 compared to 2013. Cost of revenues increased $6.7 million, or 36%, in 2013 as compared to
2012. The increase was primarily attributable to an increase of $4.7 million in service fees due to an increase in members and subscribers and a $0.9 million increase in depreciation expense as a result of opening a new data center during 2013. In
addition, there was a $0.6 million increase in personnel-related expenses due to increased headcount. The decrease in cost of revenues as a percentage of total revenues and corresponding increase in gross profit for 2013 as compared to 2012 was
primarily a result of improved pricing and efficiencies with new and existing service providers.

2011 compared to
2012. Cost of revenues increased $4.7 million, or 33%, in 2012 as compared to 2011. The increase was primarily attributable to an increase of $3.0 million in service fees due to an increase in members and subscribers. In addition, there was
a $1.0 million increase in personnel-related expenses due to increased headcount. The increase in cost of revenues as a percentage of total revenues and corresponding decrease in gross profit for 2012 as compared to 2011 was primarily a result of an
acceleration of member and subscriber growth in the second half of 2012 following an increase in advertising spend.

2012 compared to 2013. Marketing expenses increased $36.0 million, or 39%, in 2013
as compared to 2012. The increase was primarily attributable to a $31.0 million increase in advertising spend and a $4.0 millionincrease in fees paid to third-party platform providers. The decrease in marketing as a percentage of
totalrevenues in 2013 as compared to 2012 was primarily a result of an improved return on advertising spend during the period.

2011 compared to 2012. Marketing expenses increased $11.6 million, or 14%, in 2012 as compared to 2011. The increase was
primarily attributable to a $7.6 million increase in advertising spend and a $3.6 million increase in fees paid to third-party platform providers.

2012 compared to 2013. General and administrative expenses increased $3.2 million, or 51%, in
2013 as compared to 2012. The increase was primarily attributable to an increase of $1.6 million in personnel-related expenses, including an increase in bonuses and overall compensation in order to support the expansion of our infrastructure and
growth of our business. In addition, there was a $1.4 million increase in professional fees associated with the growth of our business and our plans to be a public company.

2011 compared to 2012. General and administrative expenses increased $0.6 million, or 10%, in 2012 as compared to 2011. The
increase was primarily attributable to an increase of $0.7 million in personnel-related expenses due to an increased headcount in order to support the growth of our business. In addition, there was a $0.2 million increase in allocated overhead
expenses. These increases were offset by a $0.5 million decrease in professional fees.

Other expense, net

2012 compared to 2013. Other expense, net increased $0.6 million, or 30%, in 2013 as compared to 2012. The increase was
primarily due to a $0.9 million increase in the fair value of our convertible preferred

stock warrants and a $0.2 million increase in foreign exchange loss, partially offset by a decrease of $0.4 million in interest expense due to the refinancing of our loan.

2011 compared to 2012. Other expense, net decreased $0.6 million, or 24%, in 2012 as compared to 2011. The decrease
was primarily due to a $0.7 million decrease in interest expense due to our partial repaymentof principal on an outstanding loan. In addition, there was a $0.3 million increase in the fair value of our convertible preferred stock
warrants offset by a $0.3 million decrease in other fees.

Quarterly Results of Operations Data and Key Metrics

Quarterly Results of Operations Data

We have prepared the following quarterly consolidated statements of operations data for each of the eight quarters through December 31,
2013 on a consistent basis with the audited consolidated financial statements included in this prospectus. In the opinion of management, the financial information reflects adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of this data. This information should be read in conjunction with the audited consolidated financial statements and related notes included elsewhere in this prospectus. The results of historical periods are not necessarily
indicative of the results of operations for any future period.

For a definition of members and subscribers, see Key Metrics. For a discussion of certain limitations on our member and subscriber metrics, see Industry Data and Company Metrics.

We have experienced sequential growth in subscription revenues in all quarters presented, with the exception of the three
months ended June 30, 2012. This growth was a result of attracting new and repeat subscribers. The increase in our number of subscribers coincided with higher online advertising spend beginning in the second half of 2012, as well as the release
in the second half of 2012 of our enhanced mobile apps. The sequential decline in revenues in the three months ended June 30, 2012 reflected a decrease in advertising spend in the first half of 2012, as we focused on enhancing our mobile
products as well as optimizing our approach to advertising on mobile devices. Revenues from virtual currency increased in all periods with the exception of the three months ended June 30, 2012 and 2013. Revenues from virtual currency have
fluctuated in conjunction with changes in the features or the introduction of additional premium features that require virtual currency, such as those released in the second half of 2012.

Our cost of revenues has increased in absolute dollars, but has stayed relatively constant as a percentage of total revenues, starting in the
three months ended March 31, 2013 due to improved efficiencies related to the review of member profiles. Our cost of revenues increased in the three months ended September 30, 2012 as we increased our advertising spend in the second half
of 2012 and therefore acquired additional members at a faster rate as compared to the first half of 2012.

Our marketing expenses
increased in the three months ended September 30, 2012 as we increased our advertising spend in the second half of 2012.

Our
research and development expenses have fluctuated quarterly due to the timing of hiring and the use of consultants to support continued enhancements to our service. The first quarter has historically been a key period for attracting talent resulting
in an increase in personnel-related expenses. In the first quarter of 2013, we increased our engineering headcount by 27%. In the second quarter of 2013, we decreased our use of consulting services as compared to the first quarter of 2013, which
caused those expenses to decrease slightly.

Our general and administrative expenses have fluctuated quarterly primarily due to amounts
earned under our incentive bonus program and the timing of professional service fees in order to support the expansion of our infrastructure and growth of our business.

Liquidity and Capital Resources

As of
December 31, 2013, we had cash and cash equivalents of $20.5 million. Cash and cash equivalents consist of cash and money market funds.

Our primary sources of liquidity have been the issuance of convertible preferred stock, debt financing and cash generated from operations.
From our inception through December 31, 2013, we raised total proceeds of $61.6 million through sales of our convertible preferred stock.

In February 2013, we entered into a loan and security agreement (the Loan Agreement) with Silicon Valley Bank. Under the
terms of the Loan Agreement, we were advanced $8.0 million under a term loan that matures in February 2017. We used the majority of the proceeds from the term loan to pay existing notes

payable. We are required to make monthly interest-only payments through February 2014 and, thereafter, amounts outstanding under the term loan are repayable in equal monthly installments
over 36 months. The term loan bears interest at a fixed rate of 3.75% per annum. In addition, we are obligated to pay an additional $0.5 million at the earlier of maturity or repayment of the term loan. We have the option to repay the
term loan without penalty prior to maturity. The Loan Agreement requires us to comply with certain financial and other covenants, including a requirement to maintain a specified quarterly minimum EBITDA (defined in the Loan Agreement as net income
plus interest expense, income tax expense, and to the extent deducted in the calculation of net income, depreciation expense and amortization expense). We were in compliance with these covenants as of December 31, 2013.

The Loan Agreement also permits us to draw down and maintain an outstanding balance of up to $4.0 million under a revolving line of credit.
Principal amounts outstanding under the line of credit would accrue interest at 1.00% plus the then-current prime rate. Any outstanding principal and accrued interest shall become due and payable upon expiration of the line of credit in
February 2015. Amounts outstanding under the line of credit may also be repaid without penalty prior to maturity. As of December 31, 2013, we had not drawn on the revolving line of credit and the full $4.0 million was available to be
borrowed.

In connection with the Loan Agreement, we issued Silicon Valley Bank a warrant to purchase 56,140 shares of common stock.

We believe that our existing cash and cash equivalents, cash generated from operations, and availability under our revolving line of credit
will be sufficient to meet our working capital needs, scheduled term loan payments and planned capital expenditures for at least the next 12 months. From time to time, we may explore additional financing sources which could include equity,
equity-linked and debt financing arrangements. We cannot assure you that any additional financing will be available to us on acceptable terms or at all.

Operating Activities

For 2013, we generated $12.0 million of cash from operating activities. This was primarily due to a net loss of $2.6 million that was offset
by non-cash adjustments of $5.7 million. In addition, there was a $6.9 million increase in accrued liabilities and accounts payable as well as a $4.4 million increase in deferred revenue offset by a $2.3 million increase in accounts receivable.
Accrued liabilities and accounts payable grew more quickly than our accounts receivable as our receivables typically have a relatively short collection period as compared to our payables, which are settled over a longer period.

For 2012, we used $1.2 million of cash in operating activities. This was primarily due to a net loss of $20.7 million, which was partially
offset by non-cash adjustments of $3.1 million. In addition, there was a $5.9 million increase in deferred revenue, a $5.1 million increase in our accrued liabilities primarily relating to our accrued marketing expenses, a $2.0 million increase in
deferred rent and a $1.9 million decrease in prepaid expenses primarily related to fewer television ad campaigns.

For 2011, we used $4.8
million of cash in operating activities. This was primarily due to a net loss of $12.2 million, which was partially offset by a $4.3 million increase in accrued liabilities primarily relating to our accrued marketing expenses, as well as a $2.2
million decrease in prepaid marketing expenses.

For 2013, cash used in investing activities was $1.0 million, which consisted primarily of purchases of property and equipment related to the
build-out of our data centers.

For 2012, cash used in investing activities was $6.0 million, which consisted primarily of $3.9 million of
purchases of property and equipment related to the build-out of our corporate headquarters and a $2.1 million security deposit placed in a restricted cash account as required under our corporate headquarters and data center leases.

For 2011, cash used in investing activities was $0.8 million, which consisted of purchases of equipment to support the growth of the business.

Financing Activities

For
2013, cash used in financing activities was $0.6 million. This was primarily due to payments of $1.3 million on our capital equipment leases, offset by a $0.6 million net cash inflow as result of the refinancing of our loan.

For 2012, cash used in financing activities was $3.3 million. This was primarily due to $9.0 million for the repayment of our loan, partially
offset by $5.9 million of proceeds from the issuance of convertible preferred stock.

For 2011, cash provided by financing activities was
$16.7 million. This was primarily due to $15.0 million of proceeds from the issuance of convertible preferred stock and $3.0 million of proceeds from our loan, partially offset by $1.5 million for the repayment of our previous loan.

Off Balance Sheet Arrangements

We did
not have any off balance sheet arrangements as of December 31, 2013.

The contractual commitment amounts in the table above are associated with agreements that are enforceable and legally binding. Obligations
under contracts that we can cancel without a significant penalty are not included in the table above.

Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States. The
preparation of these consolidated financial statements requires us to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. We evaluate our estimates and
assumptions on an ongoing basis and they are based on historical experiences and on various other assumptions that we believe are reasonable under the circumstances. However, actual results could differ from these estimates and these differences may
be material.

Revenue Recognition and Allowance

We generate our revenues from subscriptions and virtual currency. Revenues are recognized when the following four basic criteria for revenue
recognition have been met: (1) persuasive evidence of an arrangement exists; (2) price is fixed or determinable; (3) service is performed; and (4) collectability is reasonably assured. Revenues are presented net of taxes that are
collected and remitted to governmental authorities.

We primarily generate revenues from subscriptions to our platform. We offer our
members and subscribers one-, three- and six-month subscription plans which typically automatically renew. Subscription revenues are recognized ratably over the term of the subscription period. In certain markets, we charge activation fees at the
time a new subscriber first enrolls in our service. Activation fees are deferred and recognized on a straight-line basis over an estimated average subscriber life, which is based on historical subscriber
experience.

We also generate revenues from virtual currency. Virtual currency can be redeemed by members and subscribers for certain
premium features such as Boost, virtual gifts and special delivery of messages. Virtual currency revenues are recognized when the currency is redeemed as the services are generally provided over a very short period of time, often within the same
day.

For revenues earned through our third-party platform providers, we recognize revenues based on the gross amount paid by the customer
because we are the primary obligor, we retain the ability to set all pricing and we maintain the relationship with the customer.

Our
policy is to not grant refunds. However, there are certain instances in which refunds are granted. Since we collect most of our revenues through online credit card billing, a small portion of our members initiate chargebacks due to disputes over the
credit card statements or claims of false transactions. This chargeback activity results in refunds. The allowance for refunds and chargebacks is calculated based on historical trends and any specific risks identified in processing transactions.
Changes in the allowance are recorded against total revenues.

Fair Value of Preferred Stock Warrants

Outstanding warrants to purchase shares of our convertible preferred stock are classified as a liability on our consolidated balance sheets at
fair value using the Black-Scholes pricing model. We record the convertible preferred stock warrants at their respective fair value as of the initial grant date. Gains and losses arising from the change in fair value of the convertible preferred
stock warrants are included in other expense, net, in our consolidated statements of operations. To estimate the fair value of the convertible preferred stock warrants at each balance sheet date, the Black-Scholes pricing model contains various
assumptions, including the fair value of our business and expected volatility of our convertible preferred stock, which are subject to judgment and could differ significantly in the future. Upon completion of this offering, the then-aggregate fair
value of the convertible preferred stock warrants will be reclassified from a liability to additional paid-in capital, as these warrants will automatically convert into warrants to purchase the same amount of shares of common stock.

We measure stock-based compensation expense for personnel at the grant date fair value of the award, and recognize expense on a straight-line
basis over the vesting period. Determining the fair value of an award requires judgment.

We estimate the fair value of stock-based awards
using the Black-Scholes pricing model. The determination of the fair value of a stock-based award on the date of grant using the Black-Scholes pricing model is affected by our stock price on the date of grant as well as assumptions regarding a
number of complex and subjective variables. These variables include our expected stock price volatility over the expected term of the award, actual and projected employee stock option exercise behavior, the risk-free interest rate for the expected
term of the award and the expected dividend yield, which were estimated as follows:

Expected term. The expected term
represents the period that our stock-based awards are expected to be outstanding. The expected term was estimated using the simplified method allowed under the authoritative guidance because we do not have sufficient historical experience for
determining the expected term of the stock-based awards.

Volatility. As we do not have a trading history for our common
stock, the expected stock price volatility for our common stock was estimated by taking the average of the historical volatilities of industry peers based on daily price observations over a period equivalent to the expected term of the stock option
grants. We intend to continue to consistently apply this process using the same or similar public companies until a sufficient amount of historical information regarding the volatility of our own common stock share price becomes available.

Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield in effect at the time of
the grant for zero-coupon U.S. Treasury notes with remaining terms similar to the expected term of the options.

Dividend yield. We have never declared or paid any cash dividends and do not presently plan to pay cash dividends in the
foreseeable future. Consequently, we used an expected dividend yield of zero.

If any of the assumptions used in the
Black-Scholes pricing model changes significantly, stock-based compensation for future awards may differ materially compared with the awards granted previously.

Valuation of our Common Stock

We are required to estimate the fair value of the common stock underlying our stock-based awards when performing the fair value calculations
with the Black-Scholes pricing model. The fair value of the common stock underlying our stock options was determined by our board of directors with input from management and contemporaneous third-party valuations.

Since our common stock is not publicly traded, we valued our common stock at each grant date by considering objective and subjective
factors in accordance with the guidance in the American Institute of

Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. The assumptions used in the valuation model are based on
managements future expectations combined with managements judgment. Objective and subjective factors to determine the fair value of our common stock as of the date of each option grant included the following:

the prices, rights, preferences and privileges of our convertible preferred stock relative to those of our common stock;



our actual operating and financial performance;



current business conditions and projections;



the lack of marketability of our common stock;



the likelihood of achieving a liquidity event, such as an initial public offering or sale of our company, given prevailing market conditions;



the market performance of comparable, publicly-traded companies; and



U.S. and global economic and industry conditions and outlook.

In assessing the findings of
our third-party valuation specialist, our board of directors reviewed the specialists methods and inputs used in its valuations. There were significant judgments and estimates inherent in these contemporaneous valuations. These judgments and
estimates included assumptions regarding our future operating performance, the time to complete an initial public offering or other liquidity event and the determinations of the appropriate valuation methods. If we had made different assumptions,
our stock-based compensation expense could have been significantly different.

Our board of directors determined the fair value of our
business, or enterprise value, by using the value indicators described above under the following valuation approaches:

Discounted Cash Flow Method

In valuing our common stock, the board of directors determined the equity value of our business by considering the discounted
cash flow method (DCFM). DCFM involves estimating the future cash flows of a business for a discrete period and discounting such cash flows to present value. If the cash flows are expected to continue beyond the discrete time period,
then the terminal value of the business is estimated and discounted to present value. The terminal value is determined by using observed metrics from comparable publicly-traded companies, as well as transactions from the sale of similar companies,
both public and private, and discounting that value to the present value. The discount rate applied to our cash flows was based on a weighted-average cost of capital, which represents the blended, after-tax costs of debt and equity.

The enterprise value derived from the approach discussed above is then allocated to each of the classes of stock using either the Option
Pricing Method (OPM) or the Probability Weighted Expected Return Method (PWERM). The two allocation methods are described below:

Option Pricing Method

The OPM treats common stock and convertible preferred stock as call options on a companys equity value, with exercise prices based on
the liquidation preferences of the convertible preferred stock. Therefore, under this method, the common stock has value only if the funds available for distribution to stockholders exceed the value of the liquidation preferences at the time of a
liquidity event. The common stock is treated as a call option that gives the owner the right, but not the obligation, to buy the underlying enterprise value at a predetermined exercise price. The OPM uses the Black-Scholes pricing model to price the
call options. The OPM is appropriate to use when the range of possible future outcomes is so difficult to predict that forecasts would be speculative.

Probability Weighted Expected Return Method

The PWERM involves a forward-looking analysis of possible future outcomes. This method is particularly useful when discrete future outcomes
can be predicted at a high confidence level within a probability distribution. Discrete future outcomes considered under the PWERM included various initial public offering scenarios as follows:



a low initial public offering scenario, which was predicated on our strong growth in revenues, but in which the price the market was willing to pay for our shares was lower than anticipated;



a mid initial public offering scenario, which was predicated on our strong growth in revenues and the financial markets willingness to pay market value for our shares; and



a high initial public offering scenario, which was predicated on our strong growth in revenues and the financial markets willingness to pay a premium for our shares.

We derived an enterprise value indication under each scenario by observing revenue multiples for comparable public companies. We then applied
the selected revenue multiples based on our managements updated expectations for each scenario to our financial forecast to arrive at an enterprise value indication. In each of these scenarios, the equity value was allocated pro rata among the
shares of our common stock and each series of convertible preferred stock, which caused the common stock to have a higher relative value per share. The fair value of the enterprise using the initial public offering scenarios was weighted according
to the estimate of the probability of each scenario.

Discount for Lack of Marketability

After the enterprise value is determined and allocated to the various classes of stock using the OPM and PWERM, a discount for lack of
marketability (DLOM) is applied to arrive at the fair value of the common stock. A DLOM is applied based on the theory that an owner of private company stock has limited opportunities to sell the stock and there could be considerable
additional economic costs in terms of time and effort to find buyers, thereby reducing the overall fair value of the stock.

We have granted the following stock options with the following exercise prices and fair values
since February 2013:

In accordance with the Code, 284,858 of the shares subject to options were granted at an exercise price of 110% of the fair market value of our common stock. For more information about these awards, see Executive
Compensation2013 Outstanding Equity Awards at Year-End Table.

Based on the assumed initial public offering
price per share of $ , the aggregate intrinsic value of our outstanding stock options as of December 31, 2013 was $ million, with
$ million related to vested stock options. Since December 31, 2013, we have granted options to purchase an aggregate of 4,801,250 shares of common stock, with an aggregate grant date fair value of
$ million, which will be recognized ratably over the vesting period of the options, typically four years.

Fair Value Reassessment

In
connection with the public filing of our registration statement on Form S-1 in April 2014, and with the benefit of hindsight, we determined that it was appropriate to re-assess the fair value of the
options granted in December 2013 and February 2014 as follows:



We determined that the fair value of $7.17 per share provided by our February 2014 valuation would provide the most appropriate valuation for our common stock for the options granted in February 2014 due to the close
proximity of such awards to the date of our February 2014 valuation, which we believe better reflected information regarding the progress towards our initial public offering.



We determined that the fair value of $5.86 per share provided by our December 2013 valuation would provide the most appropriate valuation for our common stock for the options granted in December 2013 due to the close
proximity of such awards to the date of the December 2013 valuation, which we believe better reflected information regarding the progress towards our initial public offering.

Quantitative and Qualitative Disclosure about Market Risk

We have operations to support members and subscribers in the United States and internationally, and we are exposed to market risks in the
ordinary course of our business. These risks primarily include interest rate, foreign exchange risks and inflation.

Interest Rate Fluctuation Risk

The primary objectives of our investment activities are to preserve principal, provide liquidity and maximize income without
significantly increasing risk. We do not enter into investments for trading or

speculative purposes. All of our cash and cash equivalents are held in either our money market or operating account. If interest rates decline, future interest income will decline. An increase or
decrease in interest rates of 100 basis points would not have had a material impact on our operating results or financial condition as of or for 2013.

Our term loan under our Loan Agreement is at a fixed rate and, therefore, there is no interest rate fluctuation risk associated with our term
loan.

Foreign Currency Exchange Risks

A significant portion of our revenues are denominated in currencies other than the U.S. dollar, principally the Euro, the British
Pound Sterling, the Australian dollar and the Canadian dollar. A portion of our expenses are also denominated in foreign currencies, principally the British Pound Sterling, the Norwegian kroner, the Euro and the Australian dollar. The
volatility of exchange rates depends on many factors that we cannot forecast with reliable accuracy. We believe our exposure to foreign currency losses is mitigated in part because receivables and payables denominated in foreign currencies are
generally received or paid within a limited time frame, typically between three to seven days. If our foreign currency denominated cash and cash equivalents, accounts receivable, accounts payable, revenues or expenses increase, our operating results
may be more greatly affected by fluctuations in the exchange rates of the currencies in which we do business. As of December 31, 2013, we had not entered into any foreign exchange hedging contracts.

Inflation Risk

We do not believe
that inflation has had a material effect on our business, financial condition or results of operations. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price
increases. Our inability or failure to do so could harm our business, financial condition and results of operations.

We are a leading global
online dating platform with over 26 million members, including approximately 650,000 subscribers, across 80 countries as of December 31, 2013. We help our members date smarter by leveraging data generated by their actions on our platform. Our
proprietary Behavioral Matchmaking engine continuously learns from the clicks, messaging and other actions of our members in order to deliver connections that are predicted to result in mutual attraction. These connections occur on our unified
global platform, allowing our members to discover and communicate with each other from their mobile phones, tablets or personal computers. We provide our members with highly personalized online dating experiences through easy-to-use features and
adaptive technology. We were the #1 grossing dating app and a top 25 grossing app on the iPhone in the United States as of December 31, 2013. Our solution is offered to our members worldwide through our single brand and is localized in 25
languages.

We launched in 2007 with the belief that online dating would become so common that people would simply think of it as dating.
Traditionally, it was difficult for singles to discover and connect with each other because they were limited by social circles, geography and time. Today, online dating has significantly reduced these limitations and improved the opportunity for
singles to connect. While online dating has increased the number of accessible singles, we believe it has exacerbated the search problem of finding mutual attraction, which can be complex and time-consuming. According to the U.S. Census Bureau,
there were over 100 million unmarried adults in the United States in 2012, and we estimate there to be over one billion unmarried adults worldwide.

Our Behavioral Matchmaking engine is self-learning and dynamically adapts based on member actions on our platform, such as sending a message,
accepting a connection or expressing interest through certain premium features. Our technology processes these actions to present potential connections that are predicted to result in mutual attraction. As we collect more data, our algorithms are
continuously refined to enhance the effectiveness of our solution for all our members.

Our solution is easy to use and fun for our
members. Once a member enters his or her email address and basic information, he or she can discover and connect with other members right away. Our Behavioral Matchmaking engine then starts to capture data, learn preferences and personalize the
experience for that member. We offer our members multiple, distinct discovery tools such as Carousel, Search and SmartPickall powered by our Behavioral Matchmaking engine. These tools and other features, such as Boost and chat, provide our
members multiple ways to interact with each other.

We believe our solution is well suited for mobile devices. Our intuitive mobile
interface and one-touch features allow our members to engage with our platform throughout their day. The availability of our platform across mobile phones, tablets and personal computers enables our members to seamlessly move between
devices, increasing the opportunities for member engagement and real-time interactions. During 2013, members using mobile devices had an average of 32% more sessions per day than members using personal computers. We were the #1 grossing dating app
and a top 25 grossing app on the iPhone in the United States as of December 31, 2013 and our Android app has been downloaded over ten million times.

We generate revenues from subscriptions as well as virtual currency. Our member base has experienced rapid growth and we intend to continue to
scale our investments in marketing and focus our efforts on the acquisition of new members and subscribers. Our number of members grew from over 18 million as of December 31, 2012 to over 26 million as of December 31, 2013.
During the same period, our number of subscribers grew from approximately 483,000 to approximately 650,000. Our total revenues grew by 63% from $109.1 million to $178.2 million in 2012 and 2013, respectively. We had net losses of $20.7 million and
$2.6 million in 2012 and 2013, respectively.

Dating is typically episodic. A person may be single or in a relationship multiple times and for varying periods of time. Traditionally, the
ability for singles to meet was limited by social circles, geography and time. Today, technology, mobile devices and the Internet have significantly reduced these limitations and improved the opportunity for singles to connect.

At the same time, social acceptance of online dating has increased with wide adoption of technology and mobile devices in our everyday life.
This has resulted in more singles embracing online dating as a fun and effective way to meet other singles. In 1999, only 2% of American singles had used some form of online personals service, and by 2013, 38% of American single adults looking for a
relationship had used an online dating website or mobile dating app, according to the Pew Research Center.

While online dating has
increased the number of accessible singles, it has created a search problem that requires users to look through a large pool of potential candidates in hopes of finding mutual attraction. Some dating websites have tried to solve this search problem
through user-generated search constraints to narrow the number of potential matches. Other dating websites have applied psychology-based methods to attempt to eliminate the need for search altogether by recommending potential matches based on
lengthy compatibility-based questionnaires. These websites rely on time-consuming processes and potentially inaccurate self-assessments, producing static, predefined results. Others attempt to solve the search problem by limiting their members to
particular religions, ages, careers, education levels or even food preferences.

Numerous online dating websites and apps have been
created, resulting in a highly fragmented marketplace. However, few reach a critical mass of members. According to IBISWorld, the majority of dating services companies had less than 1% market share of the U.S. dating services market in 2013.

The U.S. online dating market is estimated to be $1.4 billion, according to IBISWorld. The global online dating market is significantly larger
as this estimate does not take into account international markets. We estimate there to be over one billion unmarried adults worldwidemore than ten times the number of unmarried adults in the United States. Also, we believe the proliferation
of mobile devices in both U.S. and international markets will further drive the scale and growth of online dating.

Our Opportunity

We believe that there is a significant opportunity to help singles date smarter by leveraging behavioral data. Technology platforms such as
Amazon, Netflix and Pandora have successfully used data generated by the actions of their customers to enhance their services and offer recommendations predicted to appeal to each individual customer. As customers make purchases, watch movies or
listen to music, these online services capture and learn from user behavior in order to make smarter recommendations to help customers discover products, movies and songs they might enjoy and may not find on their own.

We have applied this behavior-based approach to online dating. By leveraging behavioral data, we are able to address the complex and
time-consuming search problem created by the increased number of accessible singles made possible by online dating. However, unlike recommendations for products, movies and songs, where the products do not have to like the user who selected them,
online dating is more complex since there needs to be a two-way match based on each individuals preferences. Our data-driven approach provides predictions of mutual attraction to help members discover and connect with other members.

We provide our members with highly personalized online dating experiences through easy-to-use features and adaptive technology. We believe our
platform provides the following benefits to our members:



Personalized. We create a personalized experience for each and every member. While other online dating websites often bucket their users into predefined, static groups, our Behavioral Matchmaking engine
dynamically processes, learns and adapts to each members unique actions on our platform. As a result, members are presented with potential connections that are tailored to their preferences.



Easy. We make it easy for our members to get started quickly and focus on engaging with other members. After providing an email address and basic information, members can discover and
connect with other members right away. In addition to messaging, we offer a variety of other appealing ways to interact with other members such as winks, chat requests and virtual gifts.



Mobile. The availability of our platform across mobile phones, tablets and personal computers enables our members to seamlessly move between devices, increasing the opportunities for
member engagement and real-time interactions. Our intuitive mobile interface, with one-touch features, allows our members to engage with our platform at their convenience throughout their day.



Flexible. Our platform can be used by members throughout their dating lives. We have members who range from 18 to over 90 years old. We seek to form long-term relationships with our
members so they return to our platform each time they are looking for a new dating relationship. In 2011, 2012 and 2013, 52%, 52% and 51%, respectively, of our total bookings came from repeat subscribers, who we define as subscribers who cancel
their subscription and later return to our platform as a subscriber, and subscribers who consecutively renew their subscription.



Global. We have had a global member base since we launched our platform. Our solution is offered to our members across 80 countries in 25 languages and accepts payments in 55
currencies. Because our Behavioral Matchmaking engine learns from individual actions, it is able to reflect a members preferences irrespective of their location. In 2013, 49% of our total revenues were international, and 62% of our members
were international at the end of the year.



Authentic. We believe that the authenticity and quality of member profiles is important in creating an engaging and meaningful online dating experience for our members.
We encourage our members to validate their accounts through various means such as email, phone number and Facebook or Twitter accounts. Our member operations team is dedicated to managing the quality of member profiles by reviewing profile content
for compliance with our terms and policies.

Our Competitive Strengths



Product focus. Since inception, we have focused on developing, enhancing and optimizing our technology to simplify online dating. We aim to provide the most useful and powerful
matching technology. Although our matching technology is complex, our interface is simple and intuitive. We regularly test new features and frequently update existing features, typically with a two-week release cycle, to give our members an improved
experience on both desktop and mobile apps. As of December 31, 2013, 48% of our headcount consisted of our research and development organization.



Proprietary technology. We typically process and analyze over 45 million member actions per day through our Behavioral Matchmaking engine to dynamically address each members
preferences at scale. We believe our platform contrasts with the offerings of our competitors, which are primarily focused on applying search constraints or administering questionnaires.

Efficient global platform. We have a single platform that allows our members to access our product through their mobile phones, tablets and personal computers across 80 countries and
in 25 languages. Our unified platform allows us to cost-effectively introduce new features and updates globally.



Optimized for mobile. Mobile devices are ideal for online dating as they easily fit into our members busy lives and allow members to interact more frequently. Our product is
designed to be easy to use on small screens and enables members to sign up, engage and pay with their mobile devices. During 2013, 41% of our first-time subscriptions were purchased using mobile devices.



Large member base. Our platform served over 26 million members globally as of December 31, 2013. Our large member base of both paying and non-paying members provides
beneficial network effects leading to increased value for our members. Our members have a large pool of singles with whom they can interact and be matched. As we collect more data from these actions, our algorithms are further refined to enhance the
effectiveness of our solution for all our members.



Data-driven business operations. We perform extensive data analysis to make decisions and improve operations across multiple functions of our company, including marketing, product
development, member operations, finance and human resources. For example, we measure return on advertising spend for all advertising campaigns, test new platform features through online controlled experiments and measure effectiveness and quality of
content moderation. We believe that we can generate better, more cost-effective business results and value to our members by analyzing data and making data-driven decisions across every aspect of our business.

Our Strategy

We intend to continue to
strengthen our position as a leading global online dating platform. We have over 26 million members and intend to grow our member base with the following key strategies:



Product innovation. We seek to continuously improve our products through enhancements to our Behavioral Matchmaking engine, user interface and features. For example, in the fourth quarter of 2012,
we enhanced Boost, a feature that allows a member to drive more traffic to his or her profile, with real-time feedback. Boost has become a popular way for our members to interact and has driven an increase in virtual currency revenues.



Mobile leadership. Our platform offers real-time communications and interactions that are designed for mobile environments globally. We intend to continue to develop and introduce
mobile-optimized features, such as Carousel, that allow members to quickly view potential connections and express interest through a single touch.



Return-focused advertising. We seek to optimize for total return on advertising spend by frequently analyzing and adjusting this spend to focus on channels and markets that generate a
high return. We use numerous campaigns that allow us to quickly measure the effectiveness of our advertising spend. We intend to continue with our data-driven approach to scale and optimize our advertising spend.



Brand building. We plan to further increase our brand awareness and build trust with our members through increased public relations, social media and advertising. We believe this will
enable us to gain additional members.



Long-term member engagement. We believe our matchmaking technology and features allow us to be relevant for our members throughout their dating lives. We will continue to make it easy
for our members to return and receive an optimal experience each time they are looking for a new dating relationship.

We offer easy-to-use tools to enable our members to discover, connect and communicate with each other. Our members are able to enjoy a seamless
experience across devices. All of our members are able to create a full profile, view other members profiles and engage with other members by sending and receiving a limited number of initial messages. Our subscribers have full access to send
and receive messages through our communication platform and to use certain premium features. Our subscription plans in the United States range from approximately $30 for our one-month plan to approximately $75 for our six-month plan. The screenshots
below are illustrative and reflect key features and discovery tools on our platform.

Search. Search gives members the ability to browse profiles, click to see more details and send messages and chat requests. It also provides members with search options to refine potential
connections. Decisions members make in response to search results enhance our Behavioral Matchmaking engine, allowing us to personalize the experience for each member and increase the relevance of future recommended connections.

SmartPick. SmartPick utilizes our Behavioral Matchmaking engine to compute and deliver a potential match that remains available for 24 hours. Each SmartPick is generated after an intensive search
using our proprietary algorithm that processes each members cumulative behavioral data and delivers a personalized match. An introduction is only made once both members respond with a yes to each other.

Members can purchase, earn and redeem virtual currency to use certain premium features such as:



Boost. Boost allows a members profile to appear more prominently throughout our platform. Once boosted, the member profile is promoted to other potential connections for a selected
number of impressions.



Virtual gifts. Members can give virtual gifts such as a box of chocolates or a teddy bear. Sending a virtual gift is a fun way to signal a higher level of interest. These virtual gifts are displayed
on the recipients profile.



Special Delivery. Special Delivery allows a member to send messages that are prominently displayed to the receiving member, making these messages more likely to be noticed and read.

We believe our key technologies drive significant competitive differentiation. We have a data-driven culture and are focused on improving and
expanding the capabilities and features of our proprietary technology platform. We utilize a rapid development and release cycle based on agile methodologies that allows us to deploy new features to our members in frequent iterations.

Key elements of our proprietary technology platform include:



Behavioral Matchmaking engine. Our technology is based on our Behavioral Matchmaking engine that learns from our members actions on our platform to present potential connections
that are predicted to result in mutual attraction. We employ Markov chain (memory-less) and with-memory behavioral data systems to process and evaluate member data. As members use our platform, their actions are processed by these systems which
automatically update the scores, coefficients and other measurements for those members and all other members within the system. These calculations are then utilized in generating new potential connections for our member base. We utilize leading open
source technologies such as Hadoop, Hive and Impala to perform these functions at scale. We have built proprietary models using these Big Data tools that allow us to deliver a highly personalized experience to each and every member.



Real-time communications infrastructure. By leveraging XMPP-based technologies underlying instant messaging applications, we are able to dynamically integrate user presence status and
real-time chat features into our applications. As an example, search results and member profiles display whether members are simultaneously online, and if they are, an interactive chat interface is displayed. This real-time communications capability
is available across our platform and managed through a standard programmable interface.



Big Data systems and scalable infrastructure. Our infrastructure enables the storage and processing of extremely large datasets for use across our platform. We leverage a combination
of commodity hardware and outsourced services to efficiently expand processing capacity as needed. For hosting static member content, we leverage third-party global content delivery networks and cloud-based file storage providers. For dynamic
content, we have redundant hosted data centers located in Seattle, Washington and San Jose, California that are synchronized on a near real-time basis.



Global payment system. Our proprietary payment platform provides 21 different payment methods in 55 currencies. Our infrastructure processes payments through a number of payment
processing partners to make transactions convenient for our members. Cardholder data is encrypted and our payment system is secured behind a firewall.

Member Operations

We believe that
customer support and content moderation are critical to maintaining a positive member experience. Our member operations team provides support to both subscribers and non-subscribers and is dedicated to ensuring that our members enjoy a high degree
of satisfaction when using our platform.

Customer Support

We provide customer support through our team in San Francisco, California and outsourced providers. Customer support responds to a variety of
inquiries from members through email, live phone support, voicemail support and social media. We also post frequently asked questions on our website. We currently provide customer support in six different languages: English, French, German, Italian,
Portuguese and Spanish.

Authenticity and quality are important to our member experience. Our member operations team plays an integral role in promoting the quality of
member profiles by reviewing text and photo content for adherence to our terms and policies and working to detect fraudulent profiles. In addition to our team, we use a variety of proprietary technologies to review profiles and detect and reduce
spam and fraudulent activities.

Marketing

Our marketing teams primary focus is to efficiently attract new members and subscribers to our platform. We also focus on building brand
awareness and educating potential members about our platforms features and benefits. Our approach to marketing is iterative and data-driven. We seek to optimize for total return on advertising spend by frequently analyzing and adjusting our
spend to the channels and markets that generate a high return.

We use various media channels to advertise our platform, including
display, mobile, social and search. Our agreements with paid media channels, such as Facebook and Google, are generally subject to standard commercial terms through standard insertion orders. We typically do not have long-term commitments with
respect to the advertising that we purchase.

Research and Development

Our ability to compete depends in large part on our commitment to research and development and our ability to rapidly introduce new
technologies, features and functionality to our platform. Our research and development organization is responsible for the design, development and testing of our platform. Based on customer feedback and needs, we focus our efforts on developing new
solutions, functionality, applications and core technologies and further enhancing the usability, functionality, reliability, performance and flexibility of existing solutions and applications. As of December 31, 2013, 48% of our headcount was
in our research and development organization. We cultivate an environment of innovation among employees. For example, we have a semi-annual hack-a-thon competition, in which employees compete to develop ideas to improve the company. We foster
innovation in our newest employees through our semi-annual research and development recruiting program, which includes an exercise whereby recruits develop a new product idea as part of their training. Research and development expenses were
$6.1 million, $10.3 million and $14.8 million during 2011, 2012 and 2013, respectively.

Competition

The online dating market is rapidly evolving, highly competitive and fragmented. We face significant competition in this market and we expect
competition to intensify in the future. We compete with companies in both the United States and internationally, including Match.com, eHarmony.com and Meetic.com. We also face competition from numerous smaller companies in the online dating market,
including a large number of free websites and apps. In addition, we face competition from other online companies that offer personal ads as well as offline sources such as newspapers and offline dating services, among others.

We believe the principal competitive factors in our market include:



size and engagement of member and subscriber base;



matchmaking effectiveness;



ease of use;



brand awareness, authenticity and reputation;



level of member satisfaction and ability to respond to member needs rapidly;

ability to innovate and develop new or improved features and functionality; and



pricing of services.

We believe that we compete favorably with respect to these factors. Our
ability to remain competitive will largely depend on our ability to keep pace with the evolving needs of our members and subscribers and to continue to develop and introduce new apps and services in a timely manner that meet these needs.

Intellectual Property

The protection of
our technology and intellectual property is an important component of our success. We rely upon a combination of copyright, trade secret, trademark and patent laws, as well as domain names and contractual restrictions, to establish and protect our
intellectual proprietary rights. We generally enter into confidentiality agreements and invention assignment agreements with our employees and consultants to control access to, and clarify ownership of, our software, documentation and other
proprietary information.

As of December 31, 2013, we had one issued U.S. patent and a total of eleven patent applications in the
United States and certain foreign countries. We have a number of registered and unregistered trademarks in the United States and in certain other jurisdictions. We own the Internet domain name www.zoosk.com as well as approximately 400 related and
other domain names that could have future use in our business.

Despite our efforts to protect our proprietary rights, unauthorized
parties may attempt to copy or obtain and use our technology to develop products and services with the same functionality as our solutions. Policing unauthorized use of our technology is difficult. Our competitors could also independently develop
technologies like ours, and our intellectual property rights may not be broad enough for us to prevent competitors from selling products and services incorporating those technologies. In addition, we are currently and may in the future be subject to
claims that we are infringing, misappropriating or otherwise violating the intellectual property rights of others.

Government Regulation

We are subject to a number of U.S. federal and state and foreign laws and regulations that are applicable to Internet companies and those in
the online dating industry. These laws and regulations may involve data protection, online payment services, virtual currency, online dating, content regulation, intellectual property, taxation, protection of minors, consumer protection or other
subjects. Many of these laws and regulations are still evolving and being tested in courts and could be interpreted in ways that could harm our business. In addition, the application and interpretation of these laws and regulations often are
uncertain, particularly in the industry in which we operate.

We are also subject to, or may be subject in the future to, federal, state
and foreign laws regarding privacy and the protection of member data. Foreign data protection, privacy, consumer protection, content regulation and other laws and regulations are often more restrictive than those in the United States. There are also
a number of legislative proposals pending before the U.S. Congress, various state legislative bodies and foreign governments concerning data protection that could affect us.

Employees

As of December 31, 2013,
we had 168 employees, consisting of 22 in marketing, 80 in research and development, 44 in technical and member operations and 22 in general and administrative roles.

Our corporate headquarters is located in San Francisco, California, and consists of approximately 52,000 square feet under a lease that
expires in July 2018. We have an option to extend the lease for five years. We believe our facilities are adequate for our current needs and for the foreseeable future. However, we will continue to seek additional space as needed to accommodate our
growth. We also operate data centers in the United States pursuant to lease agreements or co-location arrangements. Our Seattle data center is operated under a master services agreement which can be terminated by either party with notice. Our San
Jose data center is operated under a lease that expires in 2018. We have an option to extend this lease for five years.

Legal Proceedings

From time to time, we are involved in various legal proceedings arising from the normal course of business activities, such as patent
infringement claims and consumer or advertising complaints. Although the results of legal proceedings and claims cannot be predicted with certainty, we are not currently a party to any legal proceedings the outcome of which, we believe, if
determined adversely to us, would individually or in the aggregate have a material adverse effect on our business, operating results, cash flows or financial condition.

Election of Officers

Our executive officers are appointed by, and serve at the discretion of, our board of directors. There are no family relationships among any
of our directors or executive officers.

In connection with this offering, our board of directors will adopt a code of business conduct and ethics that applies to all of our
employees, officers and directors, including our Chief Executive Officer, President, Chief Financial Officer and other executive and senior financial officers. Upon completion of this offering, the full text of our code of business conduct and
ethics will be posted on the investor relations section of our website. We intend to disclose future amendments to our code of business conduct and ethics, or any waivers of such code, on our website or in public filings.

Board Composition

Our business
affairs are managed under the direction of our board of directors. Our board of directors may establish the authorized number of directors from time to time by resolution. Our current amended and restated certificate of incorporation authorizes nine
directors, and our board of directors currently consists of eight directors. Six of our directors are independent within the meaning of the independent director guidelines of the NYSE. Our current amended and restated certificate of incorporation
and amended and restated voting agreement between us and certain of our stockholders provide for:



two directors to be designated by holders of our common stock, who are currently Messrs. Zadeh and Mehr;



one director to be designated by the holders of our Series A convertible preferred stock, which directorship is currently vacant;



one director to be designated by the holders of our Series B convertible preferred stock, who is currently Mr. Kamra;



one director to be designated by the holders of our Series D convertible preferred stock, who is currently Mr. Cowan; and



the remaining directors to be designated mutually by holders of our common stock and preferred stock, who are currently Mses. Alvarez and Dietz and Messrs. Epstein and Jordan.

The amended and restated voting agreement and the provisions of our current amended and restated certificate of incorporation by which all of
the members of our board of directors were elected will terminate in connection with this offering and there will be no contractual obligations regarding the election of our directors. Each of our current directors will continue to serve until the
election and qualification of his or her successor, or his or her earlier death, resignation or removal.

Classified Board of Directors

In connection with this offering, our board of directors will be divided into three staggered classes of directors. At each annual meeting of
stockholders, a class of directors will be elected for a three-year term to succeed the same class whose term is then expiring. As a result, only one class of directors will be elected at each annual meeting of our stockholders, with the other
classes continuing for the remainder of their respective three-year terms. Our directors will be divided among the three classes as follows:



the Class I directors will be Jeffrey Jordan, Alex Mehr and Shayan Zadeh, and their terms will expire at the annual meeting of stockholders to be held in 2015;



the Class II directors will be David Cowan and Deepak Kamra, and their terms will expire at the annual meeting of stockholders to be held in 2016; and

the Class III directors will be Aida Alvarez, Diane Dietz and Jeff Epstein, and their terms will expire at the annual meeting of stockholders to be held in 2017.

Each directors term continues until the election and qualification of his or her successor, or his or her earlier death, resignation or
removal. Our amended and restated certificate of incorporation and amended and restated bylaws that will be in effect upon the completion of this offering authorize only our board of directors to fix the number of directors and to fill vacancies on
our board of directors. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. This classification of our board of
directors may have the effect of delaying or preventing changes in control of our company. See Description of Capital StockAnti-Takeover ProvisionsAmended and Restated Certificate of Incorporation and Amended and Restated Bylaws
Provisions.

Director Independence

In connection with this offering, we intend to list our common stock on the NYSE. Under the rules of the NYSE, independent directors must
comprise a majority of a listed companys board of directors within a specified period of the completion of this offering. In addition, the rules of the NYSE require that, subject to specified exceptions, each member of a listed companys
audit, compensation and nominating and corporate governance committees be independent. Under the rules of the NYSE, a director will only qualify as an independent director if that companys board of directors affirmatively
determines that the director has no material relationship with the company.

Audit committee members must also satisfy the
independence criteria set forth in Rule 10A-3 under the Exchange Act. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of
the audit committee, the board of directors or any other board committee: (i) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries; or (ii) be an affiliated
person of the listed company or any of its subsidiaries. We intend to satisfy the audit committee independence requirements of Rule 10A-3 within the applicable time frame.

Our board of directors has undertaken a review of the independence of each director and considered whether each director has a material
relationship with us. As a result of this review, our board of directors determined that all of the members of our board of directors, except Shayan Zadeh and Alex Mehr, are independent directors as defined under the listing standards
and rules of the NYSE.

Lead Independent Director

Our board of directors has appointed Mr. Kamra to serve as our lead independent director upon the completion of this offering. As lead
independent director, Mr. Kamra will preside over periodic meetings of our independent directors, serve as a liaison between our Chairman and the independent directors and perform such additional duties as our board of directors may otherwise
determine and delegate.

Committees of the Board of Directors

Our board of directors has an audit committee, a compensation committee and a nominating and corporate governance committee, each of which
will have the composition and responsibilities described below upon completion of this offering. Each of the below committees has a written charter approved by our board of directors. Upon completion of this offering, copies of each charter will be
posted on the Investor Relations section of our website. Members serve on these committees until their resignation or until otherwise determined by our board of directors.

Our audit committee will be comprised of Messrs. Epstein and Kamra and Ms. Alvarez following this offering, with Mr. Epstein as the
chairman of our audit committee. Each member of our audit committee is independent other than Mr. Kamra under the current NYSE listing standards and the SEC rules and regulations. We intend to comply with the applicable independence requirements
with respect to our audit committee within the applicable time frame. Each member of our audit committee is financially literate. In addition, our board of directors has determined that Mr. Epstein is an audit committee financial
expert as defined in Item 407(d)(5)(ii) of Regulation S-K promulgated under the Securities Act of 1933, as amended (the Securities Act). This designation does not impose on him any duties, obligations or liabilities that
are greater than are generally imposed on members of our audit committee and our board of directors. Our audit committee is directly responsible for, among other things:



selecting a firm to serve as the independent registered public accounting firm to audit our financial statements;

ensuring the independence of the independent registered public accounting firm;

regulations. Our compensation committee is responsible for, among other things:

Compensation Committee Interlocks and
Insider Participation

None of the members of our compensation committee is or has been an officer or employee of our company. None of
our executive officers has served as a member of the board of directors, or as a member of the compensation or similar committee, of any entity that has one or more executive officers who served on our board of directors or compensation committee
during 2013.

In 2011, we sold shares of our Series E convertible preferred stock to entities affiliated with Bessemer Venture Partners.
Mr. Cowan, a member of the compensation committee, is a partner of Bessemer Venture Partners. We have described the amounts of these sales and purchases in more detail under the section captioned Certain Relationships and Related Party
TransactionsSeries E Convertible Preferred Stock Transaction.

In connection with the sales of our convertible preferred
stock, we entered into agreements that grant customary convertible preferred stock rights to all of our major preferred stock investors. These rights include registration rights, rights of first refusal, co-sale rights with respect to certain stock
transfers, information rights and other similar rights. All of these rights, other than the registration rights, will terminate upon the completion of this offering.

Non-Employee Director Compensation

During 2013, our non-employee members of our board of directors did not receive any cash compensation or any equity or non-equity awards.

Prior to this offering, we did not have a formal policy to provide any cash or equity compensation to our non-employee directors for their
service on our board of directors or committees of our board of directors. Other than the equity awards that we granted to Mses. Alvarez and Dietz and Messrs. Epstein and Jordan, as described below, we have not granted equity awards to members of
our board of directors. As described in Equity Compensation, following this offering all option grants to directors will contain acceleration upon a change in control, including the currently outstanding options described below.

Following this

directors existing option grant fully vests and the three-year anniversary of this offering, subject to such non-employee directors continued service to us through each vesting date. The exercise price per share for these options will be
equal to our initial public offering price.



New Director Option Grants. Each non-employee director appointed after this offering through the three-year anniversary of this offering will be granted an option to purchase that number of shares of common stock
such that the director will become vested monthly in a total of approximately 4,167 shares of our common stock between the date of grant and the three-year anniversary of this offering, subject to such non-employee directors continued service
to us through each vesting date. The exercise price per share for these options will be equal to the fair market value of our common stock on the date of grant.



Annual Option Grants. On the date of each annual meeting of stockholders (commencing with our first annual meeting of stockholders in 2015), each of our non-employee directors will be granted an option to
purchase 50,000 shares of common stock at an exercise price per share equal to the fair market value of our common stock on the date of grant. These options will vest monthly over twelve months, subject to each non-employee directors
continuous service to us. Vesting for these options will begin on the date that all prior grants have become fully vested, meaning that vesting for the first annual grant will commence on the third-year anniversary of this offering.

In addition, in connection with a change in control, all of the unvested shares subject to each non-employee
directors outstanding stock options, including with respect to options granted prior to this offering, will become fully vested immediately prior to the change in control.

The amounts reported in this column represent the grant date fair value of the stock options granted to the named executive officers during 2013 as computed in accordance with Financial Accounting Standards Board
Accounting Standards Codification Topic 718. The assumptions used in calculating the grant date fair value of the stock options reported in this column are set forth in Note 7 of the notes to our consolidated financial statements included in this
prospectus.

The amounts reported in this column represent bonuses earned by Messrs. Zadeh, Mehr and Offringa under our non-equity incentive plan for executive officers for 2013. For more information about the non-equity incentive
plan compensation for our named executive officers, see Non-Equity Incentive Plan Compensation.

Our named executive officers earned cash bonuses in 2013 pursuant to our non-equity incentive plan. Under our non-equity incentive plan, the
named executive officers were eligible to receive bonuses based on the achievement of adjusted net revenue and EBITDA targets. The portion of the target bonus tied to these company metrics would be paid starting at achievement of over 80% of
adjusted net revenue and EBITDA targets and the named executive officers could receive up to 200% of their individual target bonuses for company performance at 120% or greater of the adjusted net revenue and EBITDA targets. In the case of
Mr. Offringa, 50% of his bonus was based on an assessment of his performance by our Chief Executive Officer and President. Target bonus opportunities for our non-equity incentive plan were established by our board of directors based on
recommendations from management. For 2013, the named executive officers target bonus

opportunities were as follows: Mr. Zadeh$200,000, Mr. Mehr$200,000, and Mr. Offringa$90,000. The actual bonus payments were determined by our board of directors
in January 2014. Our board of directors determined we had exceeded the adjusted net revenue and EBITDA targets for 2013, resulting in bonus payouts at 149% of the individual targets for the amounts tied to company performance. Messrs. Zadeh and
Mehr, whose individual bonus amounts were entirely based on the achievement of company performance targets, received bonuses at 149% of their target bonus. The 50% portion of Mr. Offringas bonus tied to company performance was paid out at 149%
and the 50% portion tied to his individual performance as assessed by our Chief Executive Officer and President was determined to be achieved at 100% of his target.

Offer Letters

The initial terms and
conditions of employment for each of our named executive officers are set forth in written offer letters. The offer letters have no specific term and provide for at-will employment. Each of our named executive officers has also executed our standard
form of confidential information and invention assignment agreement. In addition, certain of our named executive officers has been granted awards under our 2007 Stock Plan which provide for certain accelerated vesting in connection with a change in
control. Such accelerated vesting is described in greater detail in Potential Payments Upon Termination or Change in Control and Employee Benefit and Stock Plans.

Represents the portion of a stock option award that qualifies as an incentive stock option (ISO) under the Code. In accordance with the Code, the ISO has an exercise price of 110% of the fair market value of
our common stock on the date of grant because each of Messrs. Zadeh and Mehr held more than ten percent of the total combined voting power of our outstanding capital stock on the date of grant.

(2)

The stock option awards held by Messrs. Zadeh and Mehr vested with respect to 1/48th of the total number of shares subject to the option on February 1, 2013 and the remaining shares subject to the option vest at a
rate of 1/48th of the total number of shares subject to the option on each month thereafter, subject to continued service to us through each vesting date. This vesting schedule reflects the combined vesting on the ISO and non-ISO portions of the
stock option awards.

(3)

Represents the portion of a stock option award that does not qualify as an incentive stock option under the Code.

(4)

1/4th of the total number of shares subject to the option vested on May 24, 2011 and the remaining shares subject to the option vest at a rate of 1/48th of the total number of shares subject to the option on each
month thereafter, subject to continued service to us through each vesting date.

(5)

1/48th of the total number of shares subject to the option vested on June 1, 2012 and the remaining shares subject to the option vest at a rate of 1/48th of the total number of shares subject to the option on each
month thereafter, subject to continued service to us through each vesting date.

(6)

1/36th of the total number of shares subject to the option vested on February 1, 2014 and the remaining shares subject to the option vest at a rate of 1/36th of the total number of shares subject to the option on
each month thereafter, subject to continued service to us through each vesting date.

In February 2014, we granted stock options to our named executive officers as follows:
Mr. Zadeh700,000; Mr. Mehr700,000; and Mr. Offringa350,000. The stock options granted to Messrs. Zadeh and Mehr vest in three tranches as follows: 100,000 shares vest in 2014; 200,000 shares vest in 2015; and 400,000
shares vest in 2016. Mr. Offringas stock option vests in three tranches as follows: 50,000 shares vest in 2014; 100,000 shares vest in 2015; and 200,000 shares vest in 2016. Each tranche of the awards granted to our named executive
officers vest in equal monthly installments during the year. In addition, the stock options granted to Messrs. Zadeh and Mehr are subject to the accelerated vesting described in Potential Payments Upon Termination or Change in
Control.

Potential Payments Upon Termination or Change in Control

In connection with an involuntary termination of employment upon or within 12 months following a change in control, Messrs. Zadeh and Mehr
will receive accelerated vesting with respect to 50% of the total number of unvested shares subject to each of their outstanding equity awards as of the date of such involuntary termination. Mr. Offringa is not entitled to accelerated vesting
with respect to any of his option awards.

Employee Benefit and Stock Plans

2007 Stock Plan

Our board of
directors adopted our 2007 Stock Plan in December 2007. Our 2007 Stock Plan was approved by our stockholders in June 2008. The 2007 Stock Plan provides for the grant of both incentive stock options, which qualify for favorable tax treatment to their
recipients under Section 422 of the Code, and nonstatutory stock options, as well as for the issuance of restricted stock awards. We may grant incentive stock options only to our employees, employees of a parent company with a majority interest
in us or employees of our majority-owned subsidiaries. We may grant nonstatutory stock options and restricted stock awards to our employees, directors and consultants of a parent company with a majority interest in us or employees, directors and
consultants of our subsidiaries. In general, the exercise price of each stock option must be at least equal to the fair market value of our common stock on the date of grant. The exercise price of incentive stock options granted to 10% stockholders
must be at least equal to 110% of the fair market value of our common stock on the date of grant. The maximum permitted term of options granted under our 2007 Stock Plan is ten years, except that the maximum permitted term of incentive stock options
granted to 10% stockholders is five years. A number of the options granted under our 2007 Stock Plan to our directors may be exercised as to all shares from the date of grant, with any purchased shares subject to our right to repurchase such shares
at the original exercise price paid for such shares. After a participants termination of service, the participant generally may exercise his or her options, to the extent vested as of such date of termination, for one month after termination.
If termination is due to disability or death, the option generally will remain exercisable, to the extent vested as of such date of termination, until the six-month or twelve-month anniversary of such termination, respectively. However, in no event
may an option be exercised later than the expiration of its term. If termination is for cause, then an option automatically expires upon first notification to the participant of such termination. In the event of a corporate transaction (as defined
in the 2007 Stock Plan), the 2007 Stock Plan provides that each outstanding option will either be (i) assumed or substituted by a successor corporation or a parent or subsidiary of the successor corporation, or (ii) terminated in exchange
for a payment of cash, securities and/or other property equal to the excess of the fair market value of the vested and exercisable portion of the option over the per share exercise of such portion. If the options are not assumed, substituted or
exchanged, each outstanding option will terminate upon the consummation of the corporate transaction.

Our compensation committee is
authorized to administer our 2007 Stock Plan. Our compensation committee has discretion to make all decisions implementing the 2007 Stock Plan, including the power to (1) determine who will receive the awards, (2) determine the fair market
value of a share of our common stock, (3) interpret the terms of the 2007 Stock Plan and the awards thereunder, and (4) specify the terms and conditions

of such awards, such as the exercise price, the number of shares subject to each award, the vesting schedule and exercisability of awards and the form of consideration payable upon exercise.

As of December 31, 2013, we had reserved 11,397,922 shares of our common stock for issuance under our 2007 Stock Plan. As of
December 31, 2013, options to purchase 498,373 of these shares had been exercised, options to purchase 7,133,825 of these shares remained outstanding and 3,765,724 of these shares remained available for future grant. The options outstanding as
of December 31, 2013 had a weighted-average exercise price of $2.72 per share. We will cease issuing awards under our 2007 Stock Plan upon the implementation of our 2014 Equity Incentive Plan. Our 2014 Equity Incentive Plan will be effective on
the date immediately prior to the date of this prospectus. As a result, we will not grant any additional options under the 2007 Stock Plan following that date, and the 2007 Stock Plan will terminate at that time. However, any outstanding options
granted under the 2007 Stock Plan will remain outstanding, subject to the terms of our 2007 Stock Plan and stock option agreements, until such outstanding options are exercised or until they terminate or expire by their terms. Options granted under
the 2007 Stock Plan have terms similar to those described below with respect to options to be granted under our 2014 Equity Incentive Plan.

2014
Equity Incentive Plan

In April 2014, our board of directors adopted and our stockholders approved our 2014 Equity Incentive
Plan. The 2014 Equity Incentive Plan will become effective on the date immediately prior to the date of this prospectus and will serve as the successor to our 2007 Stock Plan. We reserved 7,000,000 shares of our common stock to be issued under
our 2014 Equity Incentive Plan. The number of shares reserved for issuance under our 2014 Equity Incentive Plan will increase automatically on the 1st day of January of each of 2015 through 2024 by the number of shares equal to 5% of the total
outstanding shares of our common stock as of the immediately preceding December 31. However, our board of directors may reduce the amount of the increase in any particular year. In addition, the following shares will be available for grant and
issuance under our 2014 Equity Incentive Plan:



shares subject to options or stock appreciation rights granted under our 2014 Equity Incentive Plan that cease to be subject to the option or stock appreciation right for any reason other than exercise of the option or
stock appreciation right;



shares subject to awards granted under our 2014 Equity Incentive Plan that are subsequently forfeited or repurchased by us at the original issue price;

shares surrendered, cancelled, or exchanged for cash or a different award (or combination thereof);



shares reserved but not issued or subject to outstanding awards under our 2007 Stock Plan on the date of this prospectus;



shares issuable upon the exercise of options or subject to other awards under our 2007 Stock Plan prior to the date of this prospectus that cease to be subject to such options or other awards by forfeiture or otherwise
after the date of this prospectus;



shares issued under our 2007 Stock Plan that are repurchased by us or forfeited after the date of this prospectus; and



shares subject to awards under our 2007 Stock Plan that are used to pay the exercise price of an option or withheld to satisfy the tax withholding obligations related to any award.

Our 2014 Equity Incentive Plan authorizes the award of stock options, restricted stock
awards, stock appreciation rights, restricted stock units, performance awards and stock bonuses. No person will be eligible to receive more than 3,000,000 shares in any calendar year under our 2014 Equity Incentive Plan other than a new employee of
ours, who will be eligible to receive no more than 6,000,000 shares under the plan in the calendar year in which the employee commences employment. The aggregate number of shares of our common stock that may be subject to awards granted to any one
non-employee director pursuant to the 2014 Equity Incentive Plan in any calendar year shall not exceed 1,500,000.

Our 2014 Equity
Incentive Plan will be administered by our compensation committee, all of the members of which are outside directors as defined under applicable federal tax laws, or by our board of directors acting in place of our compensation committee. The
compensation committee will have the authority to construe and interpret our 2014 Equity Incentive Plan, grant awards and make all other determinations necessary or advisable for the administration of the plan.

Our 2014 Equity Incentive Plan will provide for the grant of awards to our employees, directors, consultants, independent contractors and
advisors, provided the consultants, independent contractors, directors and advisors render services not in connection with the offer and sale of securities in a capital-raising transaction. The exercise price of stock options must be at least equal
to the fair market value of our common stock on the date of grant.

We anticipate that in general, options will vest over a four-year
period. Options may vest based on time or achievement of performance conditions. Our compensation committee may provide for options to be exercised only as they vest or to be immediately exercisable with any shares issued on exercise being subject
to our right of repurchase that lapses as the shares vest. The maximum term of options granted under our 2014 Equity Incentive Plan is ten years.

A restricted stock award is an offer by us to sell shares of our common stock subject to restrictions, which may vest based on time or
achievement of performance conditions. The price, if any, of a restricted stock award will be determined by the compensation committee. Unless otherwise determined by the compensation committee at the time of award, vesting will cease on the date
the holder no longer provides services to us and unvested shares will be forfeited to or repurchased by us.

Stock appreciation rights
provide for a payment, or payments, in cash or shares of our common stock, to the holder based upon the difference between the fair market value of our common stock on the date of exercise and the stated exercise price at grant up to a maximum
amount of cash or number of shares. Stock appreciation rights may vest based on time or achievement of performance conditions.

Restricted
stock units represent the right to receive shares of our common stock at a specified date in the future, subject to forfeiture of that right because of termination of employment or failure to achieve certain performance conditions. If a restricted
stock unit has not been forfeited, then on the date specified in the restricted stock unit agreement, we will deliver to the holder of the restricted stock unit whole shares of our common stock (which may be subject to additional restrictions), cash
or a combination of our common stock and cash.

Performance awards cover a number of shares of our common stock that may be settled
upon achievement of the pre-established performance conditions in cash or by issuance of the underlying shares. These awards are subject to forfeiture prior to settlement due to termination of employment or failure to achieve the performance
conditions.

Stock bonuses may be granted as additional compensation for service or performance, and therefore, may not be issued in
exchange for cash.

In the event there is a specified type of change in our capital structure without our receipt of consideration, such
as a stock split, appropriate adjustments will be made to the number of shares reserved under

our 2014 Equity Incentive Plan, the maximum number of shares that can be granted in a calendar year and the number of shares and exercise price, if applicable, of all outstanding awards under our
2014 Equity Incentive Plan.

Awards granted under our 2014 Equity Incentive Plan may not be transferred in any manner other than by will
or by the laws of descent and distribution or as determined by our compensation committee. Unless otherwise permitted by our compensation committee, stock options may be exercised during the lifetime of the optionee only by the optionee or the
optionees guardian or legal representative. Options granted under our 2014 Equity Incentive Plan generally may be exercised for a period of three months after the termination of the optionees service to us, for a period of 12 months in
the case of death or for a period of six months in the case of disability, or such longer period as our compensation committee may provide. Options generally terminate immediately upon termination of employment for cause.

Our 2014 Equity Incentive Plan provides that, in the event of a sale, lease or other disposition of all or substantially all of our assets or
specified types of mergers or consolidations (each, a Corporate Transaction), outstanding awards under our 2014 Equity Incentive Plan may be assumed or replaced by any surviving or acquiring corporation; the surviving or acquiring
corporation may substitute similar awards for those outstanding under our 2014 Equity Incentive Plan; outstanding awards may be settled for the full value of such outstanding award (whether or not then vested or exercisable) in cash, cash
equivalents, or securities of the successor entity with payment deferred until the date or dates the award would have become exercisable or vested; or outstanding awards may be terminated for no consideration. Our board of directors has the
discretion to provide that a stock award under our 2014 Equity Incentive Plan will immediately vest as to all or any portion of the shares subject to the stock award at the time of a Corporate Transaction or in the event a participants
service with us or a successor entity is terminated actually or constructively within a designated period following the occurrence of the transaction. Stock awards held by participants under our 2014 Equity Incentive Plan will not vest automatically
on such an accelerated basis unless specifically provided in the participants applicable award agreement. In the event of a Corporate Transaction, the vesting of all awards granted to non-employee directors shall accelerate and such awards
shall become exercisable (as applicable) in full upon the consummation of the Corporate Transaction.

Our 2014 Equity Incentive Plan
will terminate ten years from the date our board of directors approves the plan, unless it is terminated earlier by our board of directors. Our board of directors may amend or terminate our 2014 Equity Incentive Plan at any time. If our board of
directors amends our 2014 Equity Incentive Plan, it does not need to ask for stockholder approval of the amendment unless required by applicable law.

2014 Employee Stock Purchase Plan

In April 2014, our board of directors adopted and our stockholders approved our 2014 Employee Stock Purchase Plan. The 2014 Employee Stock
Purchase Plan became effective upon its adoption by our board of directors but will not be in use until the completion of this offering. We have adopted a 2014 Employee Stock Purchase Plan in order to enable eligible employees to purchase shares of
our common stock at a discount following the date of this offering. Purchases will be accomplished through participation in discrete offering periods. Our 2014 Employee Stock Purchase Plan is intended to qualify as an employee stock purchase plan
under Section 423 of the Code. We initially reserved 1,500,000 shares of our common stock for issuance under our 2014 Employee Stock Purchase Plan. The number of shares reserved for issuance under our 2014 Employee Stock Purchase Plan will
increase automatically on the 1st day of January of each of the first nine years following the first offering date by the number of shares equal to 1% of the total outstanding shares of our common stock as of the immediately preceding
December 31st (rounded to the nearest whole share). However, our board of directors may reduce the amount of the increase in any particular year. The aggregate number of shares issued over the term of our 2014 Employee Stock Purchase Plan will
not exceed 15,000,000 shares of our common stock.

Our compensation committee will administer our 2014 Employee Stock Purchase Plan. Our
employees generally are eligible to participate in our 2014 Employee Stock Purchase Plan if they are employed by us for at least 20 hours per week and more than five months in a calendar year. Employees who are 5% stockholders, or would become 5%
stockholders as a result of their participation in our 2014 Employee Stock Purchase Plan, are ineligible to participate in our 2014 Employee Stock Purchase Plan. We may impose additional restrictions on eligibility. Under our 2014 Employee Stock
Purchase Plan, eligible employees will be able to acquire shares of our common stock by accumulating funds through payroll deductions. Our eligible employees will be able to select a rate of payroll deduction between 1% and 15% of their base cash
compensation. We will also have the right to amend or terminate our 2014 Employee Stock Purchase Plan at any time. Our 2014 Employee Stock Purchase Plan will terminate on the tenth anniversary of the last day of the first purchase period, unless it
is terminated earlier by our board of directors.

When an initial offering period commences, our employees who meet the eligibility
requirements for participation in that offering period will automatically be granted a nontransferable option to purchase shares in that offering period. For subsequent offering periods, new participants will be required to enroll in a timely
manner. Once an employee is enrolled, participation will be automatic in subsequent offering periods. An employees participation automatically ends upon termination of employment for any reason.

Except for the first offering period, each offering period will run for no more than 24 months, with purchases occurring every six months. The
first offering period will begin upon the date of this prospectus and will end approximately two years following the date of this prospectus. Except for the first purchase period, each purchase period will be for six months. An employees
participation automatically ends upon termination of employment for any reason.

No participant will have the right to purchase shares of
our common stock in an amount, when aggregated with purchase rights under all our employee stock purchase plans that are also in effect in the same calendar year, that have a fair market value of more than $25,000, determined as of the first day of
the applicable purchase period, for each calendar year in which that right is outstanding. In addition, no participant will be permitted to purchase more than 5,000 shares during any one purchase period or a lesser amount determined by our
compensation committee. The purchase price for shares of our common stock purchased under our 2014 Employee Stock Purchase Plan will be 85% of the lesser of the fair market value of our common stock on (i) the first trading day of the
applicable offering period and (ii) the last trading day of each purchase period in the applicable offering period.

If we experience
a change in control transaction, any offering period that commenced prior to the closing of the proposed change in control transaction will be shortened and terminated on a new purchase date. The new purchase date will occur prior to the closing of
the proposed change in control transaction and our 2014 Employee Stock Purchase Plan will then terminate on the closing of the proposed change in control.

401(k) Plan

We have established
a 401(k) tax-deferred savings plan, which permits participants, including our named executive officers, to make contributions by salary deduction pursuant to Section 401(k) of the Code. We are responsible for administrative costs of the 401(k)
plan. We may, at our discretion, make matching contributions to the 401(k) plan. No employer contributions have been made to date.

Limitations on
Liability and Indemnification Matters

Our amended and restated certificate of incorporation that will become effective in connection
with the completion of this offering contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by the Delaware General Corporation Law. Consequently, our directors will not be

personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for:



any breach of the directors duty of loyalty to us or our stockholders;



any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;



unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the Delaware General Corporation Law; or



any transaction from which the director derived an improper personal benefit.

Our amended and
restated certificate of incorporation and our amended and restated bylaws that will become effective in connection with the completion of this offering require us to indemnify our directors and officers to the maximum extent not prohibited by the
Delaware General Corporation Law and allow us to indemnify other employees and agents as set forth in the Delaware General Corporation Law. Subject to certain limitations, our amended and restated bylaws also will require us to advance expenses
incurred by our directors and officers for the defense of any action for which indemnification is required or permitted.

We have entered,
and intend to continue to enter, into separate indemnification agreements with our directors, officers and certain of our key employees, in addition to the indemnification provided for in our amended and restated certificate of incorporation and
amended and restated bylaws. These agreements, among other things, require us to indemnify our directors, officers and key employees for certain expenses, including attorneys fees, judgments, penalties, fines and settlement amounts actually
incurred by these individuals in any action or proceeding arising out of their service to us or any of our subsidiaries or any other company or enterprise to which the person provides services at our request. Subject to certain limitations, our
indemnification agreements also require us to advance expenses incurred by our directors, officers and key employees for the defense of any action for which indemnification is required or permitted.

We believe that these indemnification provisions and agreements are necessary to attract and retain qualified directors, officers and key
employees. We also maintain directors and officers liability insurance.

The limitation of liability and indemnification
provisions in our amended and restated certificate of incorporation and amended and restated bylaws may discourage stockholders from bringing a lawsuit against our directors and officers for breach of their fiduciary duty. They may also reduce the
likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholders investment may be adversely affected to the extent that we pay the
costs of settlement and damage awards against directors and officers as required by these indemnification provisions.

At present, there
is no pending litigation or proceeding involving any of our directors or executive officers as to which indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for
indemnification.

Insofar as indemnification for liabilities arising under the Securities Act, may be permitted to directors, officers or
persons controlling us, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

We describe below transactions and series of similar transactions, during our last three fiscal years, to which we were a party or will be a
party, in which:



the amounts involved exceeded or will exceed $120,000; and



any of our directors, executive officers or beneficial holders of more than 5% of any class of our capital stock had or will have a direct or indirect material interest.

Other than as described below, there have not been, nor are there any currently proposed, transactions or series of similar transactions

Amended and Restated Investors Rights Agreement

We have entered into an amended and restated investors rights agreement with certain holders of our convertible preferred stock,
including Jeff Epstein, a member of our board of directors, Canaan VIII L.P., entities affiliated with ATA Ventures and entities affiliated with Bessemer Venture Partners. These stockholders are entitled to rights with respect to the registration of
their shares following this offering under the Securities Act. For a description of these registration rights, see Description of Capital StockRegistration Rights.

Indemnification Agreements

We have
entered into indemnification agreements with each of our directors and officers. The indemnification agreements, our amended and restated certificate of incorporation and our amended and restated bylaws will require us to indemnify our directors and
officers to the fullest extent permitted by Delaware law. Subject to certain limitations, our amended and restated bylaws also require us to advance expenses incurred by our directors and officers. For more information regarding these
agreements, see Executive CompensationLimitations on Liability and Indemnification Matters.

We intend to adopt a written related person transactions policy that our executive officers, directors, nominees for election as a director,
beneficial owners of more than 5% of our common stock, and any members of the immediate family of and any entity affiliated with any of the foregoing persons, are not permitted to enter into a material related person transaction with us without the
review and approval of our audit committee, or a committee composed solely of independent directors in the event it is inappropriate for our audit committee to review such transaction due to a conflict of interest. We expect the policy to provide
that any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of our common stock or with any of their immediate family members or affiliates, in which
the amount involved exceeds $120,000 will be presented to our audit committee for review, consideration and approval. In approving or rejecting any such proposal, we expect that our audit committee will consider the relevant facts and
circumstances available and deemed relevant to the audit committee, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar
circumstances and the extent of the related persons interest in the transaction.

Although we have not had a written policy for
the review and approval of transactions with related persons, our board of directors has historically reviewed and approved any transaction where a director or officer had a financial interest, including the transactions described above. Prior to
approving such a transaction, the material facts as to a directors or officers relationship or interest in the agreement or transaction were disclosed to our board of directors. Our board of directors took this information into account
when evaluating the transaction and in determining whether such transaction was fair to us and in the best interest of all of our stockholders.

The following table sets forth certain information with respect to the beneficial ownership of our common stock at March 31, 2014, and as
adjusted to reflect the sale of common stock offered by us in this offering, for:



each of our current directors;



each of our named executive officers;



all of our current directors and executive officers as a group; and



each person, or group of affiliated persons, who beneficially owned more than 5% of our common stock.

We have determined beneficial ownership in accordance with the rules of the SEC, and such determination is not necessarily indicative of
beneficial ownership for any other purpose. Except as indicated by the footnotes below, we believe, based on information furnished to us, that the persons and entities named in the table below have sole voting and sole investment power with respect
to all shares of common stock that they beneficially own, subject to applicable community property laws.

Applicable percentage
ownership is based on 46,433,725 shares of common stock outstanding as of March 31, 2014 and assumes the conversion of all outstanding shares of preferred stock into an aggregate of 31,822,227 shares of our common stock and the exercise of an
outstanding warrant for an aggregate of 31,852 shares of our common stock. For purposes of the table below, we have assumed that
shares of common stock will be issued by us in this offering and that the underwriters will not exercise their option to
purchase additional shares. In computing the number of shares of common stock beneficially owned by a person and the percentage
ownership of that person, we deemed to be outstanding all shares of common stock subject to options held by that person or entity that are currently exercisable or that will become exercisable within 60 days of March 31, 2014. We did not deem these
shares outstanding, however, for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Zoosk, Inc., 989 Market Street, Fifth Floor,
San Francisco, California 94103.
